Pitch Your Buidl went live in Lisbon & ETHDenver

Builders pitched ideas, met teammates, and kicked off real Stacks projects at two IRL events in February.

USDCx API. Track cross-chain deposit and withdrawal status in a single query. No more scanning bridge events manually.
Stacks API. New endpoints for PoX Bitcoin transactions. Surface Bitcoin layer activity without decoding raw blocks.
⚠️ Hiro L1 API & Chainhooks v1 Deprecation. Hiro deprecated their L1 APIs (Ordinals, BRC-20, Runes, Bitcoin Indexer) and hosted Chainhooks v1 on March 9. Chainhooks v2 is available now with better performance and reliability.
