Multisig Upgrade

NEAR Multisig Upgrade

Upgrade your NEAR multisig (v1) contract to the latest version in a few clicks.

Security update available. A vulnerability was disclosed on 2026-04-05 via HackenProof. We strongly recommend upgrading as soon as possible.

Details under embargo. The full description of the issue is not public yet — the NEAR Foundation can share it on request with owners of affected multisigs. The fix itself is openly published at core-contracts/multisig/res and bundled into this app, so you can verify the contract hash matches the official release.

Outgrowing a single-chain multisig? Consider migrating to Trezu, a non-custodial multichain treasury that turns a multisig into a real treasury system — BTC, ETH, SOL, NEAR and 35+ chains from one dashboard, with confidential balances, bulk payouts, audit-ready exports, and full Ledger support. Set up in minutes at trezu.org.

Already on multisig2? You're not affected multisig2 deployments do not need to be upgraded. The app will confirm this once you sign in.
