Bitcoin Standards

TZUR for Agents is built using open standards from the Bitcoin ecosystem:

  • BIP-39: Mnemonic seed phrases
  • BIP-32: Hierarchical deterministic wallets
  • BIP-84: Native SegWit address derivation (m/84'/0'/0')
  • BIP-125: Replace-by-fee (RBF)
  • BIP-21: Bitcoin payment URIs

Network Protocol

Network communication uses the Electrum protocol for retrieving blockchain information and broadcasting transactions. Electrum servers are treated as untrusted data providers only (TLS, Merkle proofs); all signing and broadcasting happen locally. Public blockchain explorer data is provided by the BlockSight.Live API.

Agent Interface

Agents connect over the Model Context Protocol (MCP) on a local, loopback-only service (127.0.0.1). The shared Bitcoin engine (TZURCore) is the same audited core used by the TZUR wallet; it is reused as-is and never reimplemented for agents. The agent interface exposes no capability to read the seed or private keys.
