FDUSD trades almost entirely on Binance, where it serves as the quote asset for dozens of spot pairs and carries zero trading fees on seven of them. To acquire it, you either buy directly with another stablecoin on a centralized exchange or swap into it onchain through a BNB Chain or Arbitrum liquidity pool. This guide covers both routes, the chains FDUSD lives on, and the fees at each step.
Where is FDUSD liquid?
First Digital USD concentrates its liquidity on a single venue more than almost any other major stablecoin. Binance is the primary market: FDUSD is the quote currency for spot pairs spanning BTC, ETH, SOL, BNB, XRP, DOGE, and LINK, and at points in 2024 these pairs accounted for the single largest share of Binance spot volume of any stablecoin.
Circulating supply tells the same concentration story. FDUSD sits near $410 million as of April 2026 per CoinGecko, down sharply from its 2024 peak above $2.5 billion. That contraction followed an April 2025 depeg episode, when FDUSD briefly traded below $0.90 after a public solvency claim against issuer First Digital Trust. First Digital denied the claim and the peg recovered within days, but supply has stayed well below its prior high. The detail that matters for buyers: nearly all of the remaining liquidity lives on Binance and on a handful of BNB Chain DeFi pools, not spread across many exchanges the way USDC or USDT is.
Onchain, FDUSD ranks among the top three stablecoins by total value locked on BNB Chain, deployed across PancakeSwap, the Venus lending market, and most major BNB Chain money markets. PancakeSwap added five new FDUSD pools in October 2025 pairing FDUSD with ETH, BTCB, and WBNB. On Arbitrum, where First Digital Labs launched native FDUSD in June 2025, liquidity routes through Camelot.
Which chains does FDUSD run on?
FDUSD is a multichain token, but the chain you hold it on determines your fees and which liquidity you can reach. As of April 2026 it is deployed natively on five chains.
Chain | Typical transfer fee | Primary liquidity | Best for |
BNB Chain (BEP-20) | ~$0.20 | PancakeSwap, Venus, Binance withdrawals | Cheapest onchain home, deepest DeFi pools |
Ethereum (ERC-20) | $2 to $15 | DEX aggregators, lending markets | Largest downstream DeFi compatibility |
Arbitrum | ~$0.10 | Camelot | Low-fee L2 DeFi |
Solana | <$0.01 | SOL/FDUSD on Binance | High-frequency trading pairs |
Sui | ~$0.01 | Sui-native pools | Sui ecosystem apps |
The practical default is BNB Chain. Binance withdraws FDUSD over BEP-20 by default, gas runs about twenty cents, and the deepest non-exchange pools (PancakeSwap, Venus) live there. Move to Ethereum only when you need a downstream DeFi position that does not exist on BNB Chain, and accept the higher gas. Arbitrum is the low-fee alternative for L2-native DeFi through Camelot.
How to buy FDUSD on Binance
Binance is the route most buyers take because it holds the deepest order books and runs a standing zero-fee promotion on seven FDUSD pairs. The flow takes four steps once you hold a funding asset.
Fund the account. Deposit USDT, USDC, or fiat through Binance P2P or a card purchase. FDUSD has no large direct fiat on-ramp, so most buyers route through USDT first.
Open a zero-fee pair. Trade through one of the zero-fee spot pairs (BTC, BNB, ETH, SOL, XRP, DOGE, or LINK against FDUSD) to avoid the standard 0.1% maker-taker fee, then exit back to FDUSD. For a direct swap, the USDT/FDUSD book is the simplest path.
Place the order. A limit order at the $1.00 peg fills with near-zero slippage given the depth on these books.
Withdraw onchain. Select BNB Chain (BEP-20) for the cheapest exit, or Ethereum, Arbitrum, Solana, or Sui depending on where you need the token. Confirm the destination wallet supports the chain before sending.
The zero-fee pairs are a deliberate liquidity strategy: Binance subsidizes FDUSD trading to keep it as the house stablecoin against the major assets. That subsidy is why FDUSD volume punches far above its $410 million supply.
How to acquire FDUSD onchain
If you already hold stablecoins onchain and want FDUSD without touching a centralized exchange, you swap into it through a decentralized pool. The route depends on the chain.
On BNB Chain: Swap USDT or USDC for FDUSD on PancakeSwap. The FDUSD stable pools quote tight spreads because FDUSD is a top-three stablecoin by TVL on the chain. Gas costs about twenty cents.
On Arbitrum: Use Camelot, the primary venue for native FDUSD on Arbitrum since the June 2025 launch. L2 gas keeps swaps near ten cents.
On Ethereum: Route through a DEX aggregator such as 1inch or Uniswap. Liquidity is thinner here than on BNB Chain, so check the quoted slippage on larger orders before confirming.
For buyers who hold a stablecoin on one chain but want FDUSD on another, the swap and the chain hop are two separate problems. Acquiring FDUSD is a DEX swap; getting it to the chain where you need it is a cross-chain move.
Moving FDUSD across chains
Because FDUSD liquidity sits unevenly across its five chains, buyers frequently need to move it after acquisition. A position bought as a BEP-20 token on Binance often needs to reach an Arbitrum or Ethereum application. This is where stablecoin routing infrastructure matters more than the buy itself.
Eco Routes treats this as a single operation. Instead of manually bridging FDUSD from BNB Chain to Arbitrum and paying bridge fees plus two sets of gas, an intent-based route quotes one price for the full origin-to-destination move and settles it through whichever liquidity path is cheapest at execution time. For a stablecoin whose liquidity is fragmented across Binance, PancakeSwap, and Camelot on three different chains, abstracting the cross-chain step is the difference between a four-transaction sequence and a single signed intent.
FDUSD acquisition FAQ
Can I buy FDUSD with fiat directly?
There is no large direct fiat on-ramp for FDUSD. Most buyers convert fiat to USDT or USDC first (through Binance P2P, a card purchase, or a bank transfer) and then swap into FDUSD. The intermediate stablecoin step adds one trade but no meaningful cost on the zero-fee Binance pairs.
Is FDUSD available on exchanges other than Binance?
FDUSD trades on several centralized exchanges including Bybit, Gate, and others, but order-book depth outside Binance is a fraction of Binance volume. For tight spreads and fast fills, Binance and the BNB Chain DEX pools remain the practical venues as of 2026.
What does it cost to buy and move FDUSD?
On Binance, the seven zero-fee pairs let you acquire FDUSD with no trading fee; other pairs charge the standard 0.1%. Onchain swaps cost the DEX fee (typically 0.01% to 0.05% on stable pools) plus gas, which ranges from under a cent on Solana to about twenty cents on BNB Chain to several dollars on Ethereum. Cross-chain moves add a bridge or routing fee on top.
Which chain should I withdraw FDUSD to?
BNB Chain (BEP-20) is the default for cost and liquidity: about twenty cents in gas and the deepest non-exchange pools. Choose Ethereum only when a downstream DeFi position requires it, Arbitrum for low-fee L2 DeFi through Camelot, and Solana or Sui for those ecosystems specifically.
Where FDUSD routing fits
FDUSD is straightforward to buy and unusually concentrated to hold: one dominant exchange, one dominant onchain home in BNB Chain, and pockets of liquidity on Ethereum, Arbitrum, Solana, and Sui. The friction is not acquisition but movement, since the chain where you buy FDUSD is rarely the chain where you spend it. Eco Routes handles that cross-chain step as a single quoted intent, so a stablecoin acquired on Binance reaches the application that needs it without a manual bridge sequence.
