ADI Foundation zkVM Verification
The ADI Foundation is an Abu Dhabi-based organization building sovereign-grade blockchain infrastructure to help modernize public systems across emerging markets. Founded by Sirius International, the digital arm of IHC, ADI is focused on powering national-scale services that work at the policy level. The program rewards for bugs that break the soundness of the Airbender prover and its on-chain verifier(s) used by ADI’s zkEVM stack—i.e., any issue that makes an invalid state transition (or forged/incorrect proof) be accepted as valid, either in native (Rust) verification or on L1 smart contracts.
