+## Changelog
+
+### v0.2.3 (2026-04-12)
+
+- **fix**: `unwrap` calldata selector corrected from ERC-4626 `redeem(uint256,address,address)` (`0xba087652`) to `weETH.unwrap(uint256)` (`0xde0e9a3e`) — previous selector caused every unwrap to revert on-chain
+- **fix**: `stake` now validates minimum deposit of 0.001 ETH before broadcasting — previously triggered a cryptic on-chain revert
+- **fix**: `unwrap` rate fetch replaced `unwrap_or(0.0)` with explicit error propagation — RPC failures now bail with a clear message instead of silently showing "0 eETH expected"
+- **fix**: `onchainos wallet contract-call` `ok:false` responses now propagate as errors — previously silently returned `txHash: "pending"` masking simulation rejections
+- **feat**: `positions` output redesigned as human-readable table with USD valuation (ETH price via DeFiLlama coins API); USD column omitted gracefully when price API is unavailable
+- **fix**: `wrap`/`unwrap` SKILL.md corrected — weETH uses `wrap(uint256)`/`unwrap(uint256)`, not ERC-4626 `deposit`/`redeem`
