/Community Multi-sig Bridge

COOK moves between Solana and Cookie Chain through a community-operated multi-sig. It is a lock/unlock bridge, not a mint/burn bridge, and no single party can move bridge funds unilaterally.

# Flow: Solana to Cookie Chain

• Lock on Solana: the user deposits COOK into bridge vault on Solana mainnet.
• Unlock on Cookie Chain: once the threshold is met, the multi-sig authorizes the corresponding asset to unlock on Cookie Chain to the user wallet.

# Flow: Cookie Chain to Solana

In the reverse direction, the same signer set controls the corresponding unlock back on Solana. The community multi-sig coordinates bridge locks and unlocks on both sides.

# Multisig transparency

All community multisig activity, votes, and vaults controlled for the bridge can be reviewed publicly at /community.

# Solana-side multisig

The Solana side of the bridge also uses a Squads multisig. This gives the bridge a matching community-controlled coordination layer for Solana-side approvals, proposals, and vault operations.

• Multisig PDA, not a vault: E59ZcXNRRR6B9hKAxpmhF2MrmeiW7F4tJWH5NfaWToQc
• Solana bridge vault: DoYYCtcG2vfrE3HtxBBXiNVieMutvWBXsgbF3SKtYCyx
• Initial signer policy: 10 members with a 6/10 threshold.

Solana-side bridge proposals can be reviewed in Squads at app.squads.so.
