This project wraps keypairs (altbn128, secp256k1, ed25519) as an NFT on Oasis Sapphire, this allows for e.g. Bitcoin wallets to be traded by making a deposit to the NFTs Bitcoin address, the secret key is only revealed to the owner whent the NFT is burned. This acts like a 'bridgeless bridge'.
Please note: this project is a proof of concept demo, please do not use it or deploy to mainnet as-is, it is part of a larger project and does not offer privacy on its own
Development is done in a Docker container and uses a local ephemeral Sapphire node.
make sapphire-dev & # Start local Sapphire node
make dev-shell # Ephemeral docker container
> pnpm hardhat test # Test NFT implementation using OpenZeppelin tests
> make test # Run mint/burn tests against local Sapphire nodeExample mint/burn (for Ed25519):
