How it works

A simple lifecycle, enforced by the escrow program at every step.

01

Create & deposit

The buyer opens an escrow and deposits USDC or USDT into a program-owned vault. Nobody — not even BingoSafe — holds a private key to it.

02

Deliver & confirm

The seller delivers off-chain while funds stay locked. When satisfied, the buyer confirms and the program pays the seller atomically.

03

Dispute if needed

If something goes wrong, either side escalates. An arbitrator reviews the evidence and resolves with a full or partial split, enforced on-chain.

04

Timeout protection

If the seller never delivers, the deadline unlocks a refund. The buyer gets everything back — timeout refunds carry no fee.

Security is the product

Security-first design straight from the specification: strict account constraints, explicit state machines, and no private-key custody.

Program-owned vaults

Funds sit in PDA vaults with no private key. Only the escrow program's validated state transitions can move them.

Stablecoins only

USDC and USDT for predictable settlement — no volatility risk while a deal is in flight. More SPL tokens can be enabled by governance.

Fair arbitration

Disputes are resolved by a designated arbitrator with full or partial splits, executed atomically by the program.

Transparent history

Every state transition emits an on-chain event. Anyone can audit exactly what happened, and when.

Strict on-chain checks

Signer verification, explicit status transitions, checked arithmetic, and deterministic PDA seeds on every instruction.

Deadline enforcement

Deadlines are validated on-chain. Expiry unlocks a buyer refund that no counterparty can block.

Simple, honest fees

One platform fee on successful release. One arbitration fee, and only when a dispute actually escalates — which keeps disputes honest. Refunds are always free.
