Blockchains
Hackerbane audits smart contracts and protocol infrastructure across the major blockchain ecosystems. Pick your chain to see what we review there and what you get.
What these pages are
A blockchain is a shared ledger that anyone can deploy programs to, and those programs hold real value. Every chain has its own virtual machine, languages, and failure modes, so our audits start from how your chain actually works rather than from a generic checklist.
Whether it is Solidity on Ethereum, Rust on Solana, Move on Aptos, or a Cosmos SDK module, the same senior team reviews the contracts, the bridges and messages they trust, and any automation that holds a key. Don't see your chain listed? Ask – we likely support it.
Pages
- Ethereum security review
Ethereum is the largest smart contract platform and the settlement layer most of DeFi depends on. Hackerbane audits the Solidity and Vyper contracts you deploy there, the upgrade paths behind them, and the keys that control both.
- BNB Chain security review
BNB Chain, still widely searched as BSC, is an EVM-compatible chain with low fees and fast blocks. Hackerbane audits the Solidity contracts you deploy there with the economics of this chain in mind.
- Polygon security review
Polygon is a family of Ethereum scaling products: the proof-of-stake chain, zero-knowledge rollups, and the bridges that connect them to Ethereum. Hackerbane audits the contracts you deploy on each and the messages you treat as final.
- NEAR security review
NEAR is a sharded blockchain that runs contracts in WebAssembly, with human-readable accounts and per-key permissions. Hackerbane audits the Rust and JavaScript contracts you deploy there and the access keys that control them.
- Avalanche security review
Avalanche is a network with an EVM-compatible C-Chain plus custom subnets that run their own validators and virtual machines. Hackerbane audits the Solidity you deploy on C-Chain and the subnet and Warp messaging components you build yourself.
- Solana security review
Solana is a high-throughput blockchain where programs operate on the accounts a transaction passes in. Hackerbane audits Solana programs in Rust, from account validation to cross-program invocation and key management.
- Aptos security review
Aptos is a layer-1 blockchain built on the Move language, where coins and objects are typed resources with rules about who can hold or move them. Hackerbane audits Aptos Move modules and the accounts that publish and upgrade them.
- Optimism security review
Optimism is an Ethereum layer-2 rollup built on the OP Stack, the shared codebase behind the Superchain. Hackerbane audits your OP Stack contracts and the deposit and withdrawal paths that move value to and from Ethereum.
- ZKsync security review
ZKsync is an Ethereum layer-2 that settles with validity proofs and ships native account abstraction and paymasters. Hackerbane audits ZKsync Era contracts, smart accounts, and the parts of the proof system your safety claims depend on.
- Arbitrum security review
Arbitrum is an Ethereum layer-2 built on the Nitro stack, running Solidity contracts alongside Stylus programs written in Rust or C. Hackerbane audits your Arbitrum contracts, retryable tickets, and Stylus programs across One, Nova, and Orbit chains.
- Polkadot security review
Polkadot is a network of parachains that share security and move value and instructions through XCM. Hackerbane audits parachain runtimes, ink! smart contracts, and the cross-chain messages that can mint or burn on another chain.
- Cosmos security review
Cosmos is an ecosystem of sovereign chains built with the Cosmos SDK and connected by IBC. Hackerbane audits SDK modules, CosmWasm smart contracts, and the IBC packet paths that can create or move value between chains.
- TON security review
TON is a high-throughput blockchain built around asynchronous messages between contracts, with jettons as its token standard and FunC and Tact as its languages. Hackerbane audits TON contracts, from jetton minters to the bounce handlers that keep balances honest.
- Sonic security review
Sonic is the EVM-compatible successor to Fantom, built for sub-second finality. Hackerbane audits Sonic Solidity contracts with attention to what fast blocks do to time-locks, oracle heartbeats, and liquidation windows.
