Crypto On/Off-Ramp & OTC Conversion Infrastructure

Fiat-to-Crypto and Crypto-to-Fiat Conversion

Adesic provides a complete suite of fiat on/off-ramp infrastructure for individuals, businesses, and institutions seeking compliant, low-cost access to digital assets. Users can purchase USDC, USDT, Bitcoin, Ethereum, Solana, and 75+ cryptocurrencies directly from their bank account via USD wire transfer, with same-day settlement for approved transactions and full self-custody delivery to the user's own wallet.

For off-ramping, Adesic converts cryptocurrency holdings into USD and settles directly to a designated bank account — typically same-day or within 1–2 business days — supporting 75+ cryptocurrencies and stablecoins at industry-leading rates with a transparent fee structure.

Stablecoin Access

Direct access to USDC and USDT across multiple blockchain networks (Ethereum, Base, Solana, Polygon, Avalanche) at competitive rates with deep institutional liquidity, suitable for cross-border B2B transfers, payment settlement, DeFi participation, and treasury management in digital dollars.

API-Based Conversion Infrastructure

The Adesic Transaction API enables developers and platforms to programmatically move money between crypto wallets and bank accounts — supporting on-ramp, off-ramp, and wallet-to-wallet flows through a single compliant REST endpoint. Free to use with no subscription; fees apply only at transaction execution. A sandbox key is available for testing. KYC/KYB compliance is built in.
