Context

Follow-up from bridge UI verification on v0.1.82 (2a127e66, mainnet). Primary fix is confirmed: MIN label on Solana destination, destTokenDecimals loading via TokenMapping PDA (findTokenMappingPda + resolveWithdrawSrcTokenBytesForSolana), net "You will receive" line, MIN preset + CTA flows (route tested: BSC → Solana, token testa).

What still needs validation

Below-min block behavior should be exercised against live PDA limits, not only the happy path. Today testa has a 1.0 minimum, which makes the below-min edge case hard to trigger without sub-1 testa transfers (or another asset / configuration with a more testable floor).

Scope / acceptance

Attempt an actual below-min amount on a Solana destination and confirm the UI blocks or warns as designed, consistent with on-chain TokenMapping / withdraw constraints.
Document route, token, amounts, and observed behavior (screenshots or notes) for regression reference.

@PlasticDigits verified on v0.1.82 - 2a127e6.

Route: BSC → Solana
Token: tdec (18 decimals on BSC, MIN PDA 3Af1LkQo2g9xasGhCcofVnRPWJxPjSyBHnMiFdzVNRm5)
Live MIN displayed: 1.005251256281407037 tdec
Test amount: 0.0005 tdec (~2000x below MIN)

Result: BRIDGE button disabled, blocked cursor on hover. UI correctly prevents submission below MIN.

Minor UX note: button is silently disabled with no explicit error text or tooltip explaining "below MIN" — not blocking, just an observation. MIN value is shown in the header row so user has the reference.

Screenshot attached on request.

@Brouie Open an issue for the minor ux note to add tooltip and explicit error text below button explaining the reason the button is disabled, then close this issue
