They sign transactions together without ever assembling the full key, so there is no single key to steal or lose. Compared with multisig, MPC signs off-chain, so a transaction costs and looks like a normal single-key payment and the same setup works across chains. Multisig gives an on-chain audit trail instead, at the price of higher fees and per-chain support. MPC fits an operating treasury that transacts often. Multisig fits a treasury where on-chain verifiability is the requirement.<\/span><!-- notionvc: 75a240f5-9a0a-4570-b99e-debf78d51e60 --><\/p>\n    <\/div>\r<\/div>\n\n\n<p class=\"wp-block-paragraph\">Crypto wallet infrastructure is the set of systems that generate and store the keys, and sign transactions with them. The hardest part is the key. Whoever holds it controls the coins, so how you hold that key is the whole of custody. <strong>MPC custody is the model built for treasuries that transact often across chains,<\/strong> and this guide explains how it works and where its limits are.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What Is MPC Custody?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">MPC custody is a way of holding crypto where the private key is never created or stored as one whole piece. It is split into separate shares held by different parties, and they work together to approve a transaction without the full key ever existing in one place. MPC stands for multi-party computation. The same question applies to treasuries sending <a href=\"https:\/\/paybis.com\/business\/paybis-send\/\">mass crypto payouts<\/a>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How Does MPC Custody Work?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The private key is the secret that controls the coins. Whoever holds it can move the funds. A standard wallet keeps that key whole, in one place, which makes it a single thing to steal or lose. MPC custody removes that single thing. That matters for any crypto a business buys through a <a href=\"https:\/\/paybis.com\/business\/on-off-ramp\/\">crypto on\/off-ramp<\/a>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Multi-party computation is a branch of cryptography where several parties each hold a piece of a secret and compute a result together without any of them seeing the whole secret. Applied to custody, the key is generated already split into shares, each held by a separate party. To sign a transaction, each party computes part of the signature with its own share, and the parts combine into one valid signature. The full key is never put together, not even for a moment.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A set number of shares has to take part for a signature to count, so no single share, and no single person, can move funds alone.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">MPC Custody Against Multisig and Single-Key Wallets<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">All three hold crypto, but they differ in where the key lives and what can go wrong.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">How single-key wallets, multisig, and MPC custody differ.<\/p>\n\n\n\n<style>\n#pb-custody-models135 {\n  all: revert;\n  display: block !important;\n  width: 100% !important;\n  max-width: 100% !important;\n  font-family: 'Graphik', 'Inter', 'Segoe

class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>The table shows how they differ. Which one a business should run is a separate question.<\/strong><\/p>\n\n\n\n<h2 class=\"wp-block-heading\">MPC vs Multisig: Which Should a Business Use?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Neither is safer than the other. They distribute control differently, and the right choice follows from how the treasury operates.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Multisig earns its place where on-chain verifiability is the point. A static long-term treasury or a DAO (a member-governed on-chain organization) needs outside parties to verify from the chain itself who can move funds. The costs are real: higher fees per transaction, per-chain support, and signer changes that can require redeploying to a new address. The <a href=\"https:\/\/paybis.com\/blog\/multisig-corporate-treasury-governance\/\">multisig corporate treasury governance guide<\/a> covers thresholds, signer policy, and recovery.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">MPC wins for operating treasuries: frequent transactions, multiple chains, and policies that change as the team changes. Signing happens off-chain, so every payment costs and settles like a normal transfer. The same control model covers every supported chain, and share rotation handles joiners and leavers without moving funds. The trade-off is that the approval trail lives in the custodian&#8217;s policy engine rather than on-chain. That makes the provider&#8217;s logging and attestation practices part of the security model.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In practice many institutions run both. MPC covers the operational account that pays and receives weekly. Multisig or deep cold storage holds reserves that should be slow to move by design.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Why Does MPC Custody Matter for a Business?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Because it removes the risk that a single lost key or a single insider can drain the treasury. The <a href=\"https:\/\/paybis.com\/blog\/payout-security-in-crypto\/\">payout security and custody models<\/a> guide covers fund protection for payouts too. No one person holds the means to move funds, so the coins cannot leave without the required shares taking part. That is the control an auditor looks for, and the reason MPC suits an operating treasury.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It also stays practical at scale. Because the signing work happens off the chain, a transaction looks and costs like a normal one, and the same method works across many chains rather than depending on each chain&#8217;s support for multisig.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Is MPC Custody Safe, and What Are Its Limits?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">MPC custody is strong, but it is not the whole of security. It removes the single-key weakness. It does not replace the controls around it, like the policies for who can request a transaction and how access is managed. Infrastructure and operational compromise accounted for about 76% of all crypto funds stolen in the first half of 2026, against about 15% of incidents ( per <a href=\"https:\/\/www.trmlabs.com\/resources\/blog\/h1-2026-crypto-hacks-reach-record-high-as-losses-fall-below-usd-1-billion\">TRM Labs H1 2026 data<\/a>). MPC is one strong control, not a complete defense on its own.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What Should an Enterprise Check Before Choosing MPC Custody?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Six questions separate marketing from substance when evaluating an MPC provider:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Share distribution<\/strong>: who holds the key shares, across what infrastructure, and in how many jurisdictions? Shares held on one cloud account defeat the purpose.<\/li>\n\n\n\n<li><strong>Policy engine<\/strong>: can transaction limits, approver lists, and velocity rules be set per account, and who can change them?<\/li>\n\n\n\n<li><strong>Independent assurance<\/strong>: what external assurance covers the provider, from regulatory authorisation and supervision through to security certifications and audit reports, and what can be shared on request?<\/li>\n\n\n\n<li><strong>Recovery<\/strong>: what is the documented procedure if a share holder is compromised or unavailable, and has it been tested?<\/li>\n\n\n\n<li><strong>Regulatory position<\/strong>: is the provider authorized for custody in the jurisdictions that matter to the business? Paybis holds an EU MiCA CASP authorisation (27-55\/2026\/6), issued by the Bank of Latvia in May 2026.<\/li>\n\n\n\n<li><strong>Asset and chain coverage<\/strong>: does the custody model cover every asset the treasury actually holds, natively rather than through a wrapped version of the asset?<\/li>\n<\/ol>\n\n\n\n<h2 class=\"wp-block-heading\">How Paybis Uses MPC Custody<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Paybis secures crypto with MPC custody, so the key that controls a company&#8217;s crypto is split across parties and never sits whole in one place. It covers the major assets and the main chains a business uses, and it sits inside one account alongside the company&#8217;s fiat. Paybis compares <a href=\"https:\/\/paybis.com\/blog\/best-corporate-crypto-account-platforms\/\">corporate crypto account platforms<\/a> side by side.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Assets held.<\/strong> BTC, ETH, SOL, <strong>USDT,<\/strong> and USDC.<\/li>\n\n\n\n<li><strong>Chains supported.<\/strong> Ethereum, <strong>Tron,<\/strong> Polygon, and Base, so the same custody method covers <a href=\"https:\/\/paybis.com\/blog\/multi-chain-crypto-payout\/\">the main chains<\/a> businesses pay out on.<\/li>\n\n\n\n<li><strong>No single point of failure.<\/strong> The key is split into shares, so no one person can move funds alone.<\/li>\n\n\n\n<li><strong>Held in one account.<\/strong> Custody sits inside the <a href=\"https:\/\/paybis.com\/blog\/corporate-crypto-account\/\">Paybis Global Account<\/a>, so a company&#8217;s crypto and cash are held and seen in one place.<\/li>\n\n\n\n<li><strong>For a company&#8217;s own money.<\/strong> The account is built for a company&#8217;s own corporate crypto.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n\n  <div id=\"pb-mpc-stats\" style=\"font-family:'Graphik','Inter','Segoe UI',system-ui,sans-serif;display:grid;grid-template-columns:repeat(auto-fit,minmax(150px,1fr));gap:12px;margin:24px 0;\">\n    <div style=\"background:#090B1C;color:#fff;border-radius:12px;padding:18px 20px;\">\n      <div style=\"font-size:24px;font-weight:700;\">MPC<\/div>\n      <div style=\"font-size:12px;color:#A4A7E3;letter-spacing:.04em;\">split-key custody<\/div>\n    <\/div>\n    <div style=\"background:#090B1C;color:#fff;border-radius:12px;padding:18px 20px;\">\n      <div style=\"font-size:24px;font-weight:700;\">5<\/div>\n      <div style=\"font-size:12px;color:#A4A7E3;letter-spacing:.04em;\">major assets<\/div>\n    <\/div>\n    <div style=\"background:#090B1C;color:#fff;border-radius:12px;padding:18px 20px;\">\n      <div style=\"font-size:24px;font-weight:700;\">4<\/div>\n      <div style=\"font-size:12px;color:#A4A7E3;letter-spacing:.04em;\">chains<\/div>\n    <\/div>\n    <div style=\"background:#090B1C;color:#fff;border-radius:12px;padding:18px 20px;\">\n      <div style=\"font-size:24px;font-weight:700;\">1<\/div>\n      <div style=\"font-size:12px;color:#A4A7E3;letter-spacing:.04em;\">account for cash and crypto<\/div>\n    <\/div>\n  <\/div>\n\n  \n\n\n\n<h2 class=\"wp-block-heading\">Bottom Line<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Crypto custody comes down to how you hold the keys. A whole key in one place is one thing to lose. MPC custody splits the key into shares, so no single share, and no single person, can move funds, while a transaction still looks and costs like a normal one. It is the model built for an operating treasury, and the one Paybis uses to secure a company&#8217;s own crypto inside one account.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Key Terminology<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Private key<\/strong>: The secret that controls the coins at an address.
