Adesic

Adesic is a US-based crypto financial infrastructure company founded in 2020 and headquartered in Providence, Rhode Island. The company builds products and APIs that sit at the intersection of traditional finance and the blockchain economy, enabling individuals, businesses, and developers to buy, sell, and move cryptocurrency with ease, compliance, and low fees.

Core Products and Services

Adesic's platform covers the full spectrum of crypto money movement. At its core are crypto on-ramps and off-ramps that let users purchase stablecoins such as USDC and USDT directly via USD wire transfers, or convert crypto holdings back to fiat and receive funds in a bank account — typically same-day. The company emphasizes a self-custodial model: Adesic transmits funds between banks and wallets but never takes custody of user assets beyond the transaction window.

For developers and fintech companies, Adesic provides three distinct APIs:

• Transaction API — a free REST API for embedding crypto-to-fiat and fiat-to-crypto transfers directly into third-party products, supporting B2B and B2C payment flows with sandbox testing

• Crypto API — real-time and historical market data from 100+ exchanges and 100,000+ cryptocurrencies, with WebSocket streaming, price alerts, and pay-as-you-go credits

• Blockchain API — on-chain data from decentralized exchanges including Uniswap and SushiSwap, covering liquidity pools, token info, and DeFi trade data

Business-focused solutions include crypto payments (accept crypto and auto-convert to USD), crypto payroll (pay employees in crypto globally), and treasury management (corporate crypto portfolio management). An institutional OTC trade desk serves clients with transaction volumes typically above $50,000, offering white-glove execution, deep liquidity sourcing, and same-day settlement.

Key Strengths

Adesic positions itself as compliance-first infrastructure: all accounts require KYC/KYB verification, and the platform is licensed for money transmission. The self-custody design means businesses retain control of their assets. The Transaction API is offered free of charge, with fees only applied at execution. The company supports 75+ cryptocurrencies and stablecoins across multiple blockchains including Ethereum, Solana, Base, Cardano, Polygon, and Avalanche.

Notable Clients and Investors

Adesic has received investment from Boost VC and Qubic Labs. Client testimonials reference co-founders of Web3 startups and members of blockchain industry councils. The company serves a mix of individual users, startups, enterprises, and private clients including trusts, family offices, and high-net-worth individuals.

Why Choose Adesic

Adesic combines developer-grade APIs with direct fiat-to-crypto rails, making it suitable for fintech builders who need programmatic money movement as well as businesses that want to accept crypto or pay employees in digital assets. Its transparent fee structure, compliance-first approach, and self-custody design address common friction points in institutional and corporate crypto adoption.
