Arbitrum One delivers Ethereum-grade security at a fraction of the cost. AI agents on Arbitrum pay pennies per transaction, tap GMX perpetuals natively, access Uniswap v3 deep liquidity, and hold USDC issued directly by Circle. Purple Flea gives your agent a full Arbitrum wallet and REST API with no wallet setup, no KYC, and no infrastructure to manage.
Arbitrum One is the leading Ethereum Layer 2 by total value locked, consistently surpassing $15 billion in assets secured under Ethereum's consensus while charging a fraction of mainnet fees. For AI agents that need to transact frequently — checking positions, rebalancing portfolios, paying for data feeds, or routing payments between counterparties — Arbitrum is the chain where economics work. A transaction that costs $5–20 on Ethereum mainnet costs $0.01–0.10 on Arbitrum One.
The fee advantage alone would make Arbitrum compelling, but the ecosystem seals the deal. GMX, the largest on-chain perpetuals exchange in DeFi by open interest, is native to Arbitrum. Agents running trading strategies — trend-following, funding rate arbitrage, delta-neutral hedging — can access real futures markets with deep liquidity and low slippage without ever leaving Arbitrum. Purple Flea's Hyperliquid API handles similar strategies off-chain; GMX on Arbitrum handles them fully on-chain with Ethereum-level settlement guarantees.
Uniswap v3 on Arbitrum offers deep spot liquidity across ETH, WBTC, ARB,
USDC, LINK, and hundreds of other ERC-20 tokens. USDC on Arbitrum is
natively issued by Circle, making it the canonical stablecoin for agent treasuries. The ARB
governance token adds a native asset for agents participating in the Arbitrum DAO or
receiving grants. And because Arbitrum is fully EVM-compatible, any Purple Flea tool that
works on Ethereum mainnet works identically on Arbitrum — same ABI encoding, same
ethers.js calls, same REST endpoints.
Everything an AI agent needs to operate on Arbitrum One, via a single REST API.
Spin up a non-custodial BIP-44 Arbitrum wallet in one API call. Receive ETH, USDC, ARB, GMX, and any ERC-20. Your agent owns its keys; Purple Flea signs on your behalf.
Transfer ETH, USDC, ARB, WBTC, LINK, and any ERC-20 on Arbitrum. Gas is estimated automatically using EIP-1559 fees. Confirmations typically arrive in under 2 seconds.
Open and manage leveraged positions on GMX's ETH, BTC, and LINK perpetual markets. Access real on-chain futures without centralized exchange KYC or counterparty risk.
Swap any token pair available on Uniswap v3's Arbitrum deployment. Purple Flea finds optimal routes, handles ERC-20 approvals, and submits the transaction on your agent's behalf.
Fetch ETH balance, any ERC-20 balance, open GMX positions, Uniswap v3 LP positions, and pending transaction status. All aggregated into a single structured API response.
Bridge assets between Ethereum mainnet and Arbitrum via the official Arbitrum bridge or third-party aggregators. Move USDC, ETH, and other tokens in both directions from your agent.
The largest on-chain perps DEX, natively available through Purple Flea's Arbitrum API.
GMX is the dominant perpetuals DEX on Arbitrum, with over $500 million in total value locked and consistently high open interest across BTC, ETH, and LINK markets. Unlike centralized exchanges, GMX positions are settled on-chain with Arbitrum's Ethereum-backed security. Your agent's collateral sits in verifiable smart contracts, not in an exchange's custody.
GMX v2 introduced isolated markets, dynamic fee tiers, and improved oracle pricing via Chainlink and custom price feeds. Purple Flea's GMX integration wraps the v2 order router, handling position sizing, collateral management, and take-profit/stop-loss orders. Agents running funding rate arbitrage strategies can compare GMX funding rates directly against Purple Flea's Hyperliquid API data to identify cross-venue opportunities.
Long or short ETH, BTC, and LINK with up to 50x leverage on GMX v2. Set collateral in USDC or ETH. Purple Flea handles position sizing and slippage limits.
Provide liquidity to GMX by minting GLP tokens. GLP earns 70% of GMX protocol fees in ETH and esGMX. Purple Flea automates GLP mint/burn and reward claiming for yield agents.
Poll GMX hourly funding rates alongside Purple Flea's Hyperliquid funding data to find arb opportunities. Long underfunded, short overfunded, collect the spread.
