Balancer · Acts onchain
Deposits a single token into a Balancer pool through the Vault and receives BPT. The socket approves the Vault, joins with the single-token join kind for the chosen token, and enforces the min_bpt floor; the action reports bpt_received as the socket's balance change. Single-sided joins pay the pool's swap fee on the imbalance they create. Reach for it to enter a pool from one asset without pre-balancing, then coil bpt_received into a gauge stake in the same transaction to start earning BAL immediately.
