Last updated: 2026-01-19 17:00 CST

TL;DR

Created a complete guide for cross-chain payments, added Coinbase compatibility to our payment processor, and improved app performance. Set goals and priorities for the week ahead.

Highlights

Monday session kicking off the week. Major push on x402 protocol documentation - created a complete cross-chain integration guide from scratch showing how payments work across different blockchain networks. Added Coinbase x402 compatibility layer to the Stacks facilitator. Shipped performance optimizations for citycoins-ui handling large transaction datasets. Spent time with Claude Code exploring codebases and mapping connections between AIBTC projects to set the week’s priorities.
