Node-DLC is a an implementation of Bitcoin DLC Protocol in the Node.js runtime, with CET signature generation achieved with cfd-dlc wrapper (written in C++).
- @node-dlc/cli
- @node-dlc/core
- @node-dlc/logger
- @node-dlc/messaging
- @node-dlc/rocksdb
- @node-dlc/transport
Many elements of the project as well as components are inspired by Node-Lightning, an Node.js implementation of the Bitcoin Lightning Network. The project also uses several packages such as:
- @node-lightning/bitcoin
- @node-lightning/bufio
- @node-lightning/core
- @node-lightning/crypto
- @node-lightning/gossip-rocksdb
- @node-lightning/logger
- @node-lightning/wire
@node-dlc/messaging and @node-dlc/core packages implement many aspects of the DLC Specification
Note: These packages contains functionality for message generation, serialization and deserialization and contain no logic for wallet functionality For DLC wallet functionality, you can check out Chainify-Finance which uses Node-DLC messaging functionality and Liquality Chainify wallet functionality to enable easy creation of wallets with the capability of entering into DLCs.
Implemented features:
- Dlc Offer, Accept, Sign V0 message support
- Oracle Announcement and Attestation V0 message support
- ContractInfo V0 and V1 message support (multi oracle message support)
- Enum Event Descriptor and Digit Decomposition Event Descriptor V0 message support
- Numeric Outcome message and payout generation support
- Polynomial (linear) payout message and curve support
- Hyperbola (1/x) shaped payout message and curve support
- Dlc Close V0 message support from mutual close proposal
Missing features:
- Backwards compatibility with (messaging and serialization proposal)[discreetlogcontracts/dlcspecs#171]
- V0 Oracle Changes message types proposal
