AMOUNT_TOO_SMALL

Where it comes from: GET /v1/quote (amount 0); also mapped from provider errors (for example Relay AMOUNT_TOO_LOW).

Causes#

• amount is "0".
• The amount does not cover the route's fixed costs (bridge fees, destination gas).
• The amount was sent in human units instead of base units ("1" USDC means 0.000001 USDC).

How to fix#

• Send base units: 1 USDC is "1000000" (6 decimals), 1 SOL is "1000000000" (9 decimals).
• Increase the amount; cross-chain routes need more than same-chain swaps.
