List wallet currencies
Returns currently available wallet currency choices and their metadata. Bank currency availability follows bank-payment support available to the authenticated API-key owner. USD discovery is unchanged. Bank currencies include the current integer deposit_fee_bps (35 = 0.35%, zero = no fee); USD omits it. Use this response to populate currency choices; existing owned wallet balances remain readable independently. CNGN settles into NGN; USDT and USDC settle into USD.

List wallet currencies
USDT and USDC settle into the USD wallet; CNGN settles into the NGN wallet. They are not separate wallet currencies.
Bank currencies include deposit_fee_bps: 35 means 0.35%, and 0 means no bank-deposit fee. Display deposit_fee_bps / 100 as a percentage. Deposit fee amounts round upward to the smallest currency unit. USD omits this currency-level field; use settlement-route metadata for route-specific fees. Discovery reports the current policy for new deposits; accepted deposits retain their captured policy.
