for better understanding of how bitcoin works, i decided to build a fork called TETSUO. bitcoin uses secp256k1 ECDSA with SHA256/RIPEMD160 hashing for addresses and transaction signing. TETSUO maintains that exact same cryptographic foundation, we inherit decades of security research. but we optimized the transaction format: - sequence numbers set to 0xffffffff for full script compatibility - SIGHASH_ALL appended to the signing preimage before hashing (not after) - proper little-endian encoding throughout this meant rebuilding the entire signing pipeline. started by forking the bitcoin-core codebase, then built a complete TypeScript wallet SDK on top. implemented BIP39 mnemonic generation, UTXO selection, fee estimation, all the stuff wallets need. the critical part: client-side signing only. your private keys never touch any server. transaction is built locally, signed locally, broadcast to network. open source: (the node) (the SDK) (block explorer) understanding bitcoin meant understanding every layer of the protocol.

just told my agent(AgenC) on telegram: "send 0.1 SOL from my ledger to this address" it did but it couldn't move a single lamport until I approved it on the Ledger Flex. clear-signed, over BLE. that's the point: the agent runs autonomous on Solana mainnet marketplace, but the keys never leave the hardware. LLMs gave us intelligence, agents gave us action and hardware gives us control. >built on Ledger Agent Stack. 👉 join:
