MeterCall

Why teams leave Lightning Labs for MeterCall

Lightning Labs' L402 and Taproot Assets are the serious BTC-native path for agent micropayments. MeterCall uses x402 (HTTP 402 over EVM + stable assets) across a 2,400-module catalog.

Where Lightning Labs still wins

  • Bitcoin purity. If your thesis is BTC-only micropayments, L402 + Lightning is ideologically cleaner.
  • Taproot Assets. Issuing any asset on Lightning is powerful for specialized use.
  • Protocol RFC quality. L402 is well-specified.

L402 and x402 are siblings — different assumptions. L402 for BTC-native, x402 for stables + EVM. The 402-economy is bigger than either of us.

Where MeterCall wins — with specifics

  • Catalog. MeterCall has 2,400 modules. L402 adopters can be counted.
  • Stablecoin settlement. Most agent-pay use cases prefer USDC/USD over sat-denominated pricing.
  • EVM reach. Your agent probably already lives on an EVM wallet — x402 slots in natively.

Migrate from Lightning Labs

Run both if you need to. Use MeterCall for your broad catalog pay; keep Lightning for BTC-native micro-flows.
