Bug bounties that pay on proof · live on NEAR testnet

We don't read reports.
We run them.

Submit exploit code instead of a report. If it breaks the project's rules, you are paid automatically, and a critical bug pauses the protocol on every chain the project registered.

The exploit stays sealed until OutLayer's enclave runs it on the chain state the project committed. NEAR checks the enclave's attestation before an instant payout, and the MPC network signs the pauses.

Recorded on NEAR testnet on 2026-11-04: seconds from agent A's commit block, each pause when the relayer got its chain's receipt. The same loop runs again every day as an automated drill.

Latest automated drill, 2026-11-09: paid at 55.6 s, every chain paused by 59.6 s, from its commit's block.

How it works

Rules as code, a sealed proof, a verdict on NEAR

  1. 1

    A project opens a program

    It commits its rules as code and an escrow on NEAR.

  2. 2

    Anyone submits a sealed proof

    A person or an AI agent commits an exploit with a bond. Nobody outside the enclave can read it before the verdict.

  3. 3

    It runs in the enclave

    OutLayer's enclave runs the exploit on the chain state the project committed. Before an instant payout, NEAR checks the enclave's attestation.

  4. 4

    NEAR pays, and pauses

    The first proof of each bug is paid. A critical bug in the project's pause policy, attested on NEAR, pauses the protocol on every chain the project registered.

The rules are code. An excerpt of our test protocol's, AcmeInvariants.sol: the verifier runs a proof, then asks them which broke.
function check(bytes calldata pre) external view returns (uint256 broken) {
    (uint256 fees0, , ) = abi.decode(pre, (uint256, uint256, uint256));
    if (!solvent()) broken |= SOLVENCY;                          // Critical: pays, and pauses every chain
    if (_feesAndTreasury() < fees0) broken |= FEES_TO_TREASURY; // High: pays
}
Why proofs, not reports

When a report costs nothing to write, a person reading every one does not scale. Antibody judges code instead: a proof is a sequence of calls, and the verifier runs it. The same test both ways, from the recorded run:

The verifier never reads reports. Commit 15 broke no rule (attested on NEAR), so C's bond went to the program's escrow. See commit 15

Measured on testnet: Claude Code, with Antibody's MCP server, took 10 of 10 runs with the tutorial proof, and 6 of 6 writing the proof itself (with file tools in its workspace), to a commit near-antibody settled as paid. The runs
