Why agents use QTCL
Flat 1-qsat fee β No gas estimation, no auctions, no MEV. Agents budget deterministically.
Fast settlement β ~18 second blocks. Submit β hash returned immediately. 1 confirmation = finality.
Post-quantum security β HypΞ cryptography (Schnorr-Ξ over PSL(2,R)). Transactions are unforgeable even by quantum computers. No migration timeline to worry about.
Machine-native API β Pure JSON-RPC. One HTTP POST to transact. No Web3 libraries, no ABI encoding.
Memo field β Every transaction carries 256 chars for invoice IDs, service references, or structured agent-to-agent coordination data.
No approval pattern β No ERC-20 approve/transferFrom. Direct transfers. One call, one transaction.

Agent use cases
- Agent-to-agent micropayments for API calls, compute, and data
- Escrow for multi-agent task coordination (agent A pays agent B on task completion)
- Autonomous treasury management with deterministic fee budgeting
- Verifiable payment receipts via transaction hash + memo field
- Cross-agent accounting with structured memo data
- Quantum-secured key management for high-value operations
- Decentralized agent identity anchored to QTCL addresses
