Six open protocols built on Bitcoin for signing, encrypting, voting, timestamping, delegating authority, and making commitments. Users sign with a Bitcoin
Overview
orangecheck provides six open protocols built on Bitcoin: Attest (prove address ownership), Lock (encrypt to a Bitcoin address), Vote (weighted polls in sats), Stamp (prove who signed something and when), Agent (give software scoped permissions), and Pledge (make promises backed by bitcoin). Each protocol works the same way: sign with a Bitcoin address, and anyone can verify the result against Bitcoin on their own machine without needing to trust orangecheck's servers. The company also operates ochk.app, a single account backed by Bitcoin that lets people sign in, back their account with bitcoin, and get paid in sats by apps that choose to pay. All protocol tools are free, and every spec is public under MIT license.
Feature summary
- Bitcoin-backed accounts

Q&A
- Do coins move when I create a proof?
- No. No protocol broadcasts Bitcoin transactions - every protocol signs messages and reads chain state but never writes to it. Your funds never leave your wallet to make a proof. The only exception is ochk.app, which is currently in testing and holds the sats that apps pay users.
- Is this custodial?
- The protocols are not custodial. No protocol requires a third party to hold funds, keys, or signatures. However, ochk.app is an exception while in testing - orangecheck holds what users earn there and holds the sign-in key for accounts made with email, Google, or GitHub.
- Which wallets work with orangecheck?
- Any wallet that signs with BIP-322 or legacy signmessage format (BIP-137) works. Browser wallets include UniSat, Xverse, Leather, OKX, and Phantom. Desktop wallets include Sparrow, Bitcoin Core, and Electrum. Hardware wallets via PSBT flow include Coldcard, Trezor, and Ledger.
- Can I self-host the verification tools?
- Yes. Every protocol's reference implementation is MIT-licensed and runs on your own infrastructure with no hosted dependency. OC Attest's SDK is a complete local verifier that needs nothing from ochk.io.
- Why Bitcoin and not Ethereum?
- Bitcoin's opportunity cost is real, measurable, and adversary-agnostic. Ethereum gas is volatile and most non-Bitcoin stake proofs involve governance tokens that can be inflated or forked. Bitcoin UTXOs provide the cleanest economic signal on the open internet.
