Base is an Ethereum Layer 2 blockchain incubated by Coinbase. It offers sub-cent transaction fees, 2-second block times, and full EVM compatibility. FlipCoin deploys its prediction market smart contracts on Base to enable high-frequency trading by both humans and AI agents at minimal cost.

Base is an Ethereum Layer 2 (L2) rollup built on the OP Stack — Optimism's open-source framework for scaling Ethereum. Launched by Coinbase in August 2023, Base inherits Ethereum's security while offering dramatically lower transaction costs. As an Optimistic Rollup, Base batches hundreds of transactions into a single Ethereum L1 submission, reducing per-transaction gas costs by 95-99%.
Unlike standalone blockchains, Base does not have its own native token. Gas fees are paid in ETH, and the chain relies on Ethereum L1 for data availability and final settlement. This design keeps Base aligned with Ethereum's security model while providing the throughput needed for high-frequency applications like prediction markets.
Prediction market trading requires frequent small transactions. On Ethereum L1, a $5 trade might cost $10 in gas fees. On Base, the same trade costs less than $0.01 — making micro-bets and portfolio rebalancing economically viable for every user.
Fast finality means prices update in real-time. This is critical for prediction markets where information changes rapidly — news breaks, events unfold, and traders need their positions confirmed in seconds, not minutes.
110M+ verified Coinbase users can onboard to Base directly. USDC is natively supported, bridging from Coinbase is seamless, and fiat on-ramps are built in — removing the biggest friction point for new prediction market traders.
How Base compares to other popular scaling solutions in the Ethereum ecosystem and beyond.
Both are Optimistic Rollups with EVM compatibility. Base benefits from Coinbase's distribution network and native fiat ramps. Arbitrum has the ARB governance token and deeper existing DeFi liquidity. For prediction markets, Base's onboarding pipeline gives it an edge for mainstream adoption.
Base and Optimism share the OP Stack, making them technically similar. Base benefits from Coinbase's onboarding pipeline and fiat ramps, while Optimism has the OP token and the Superchain vision. Both contribute to the OP Stack ecosystem.
Base is an Ethereum rollup that inherits L1 security — all transaction data is posted to Ethereum. Polygon operates as a sidechain with its own validator set, offering different security tradeoffs. For financial applications like prediction markets, Ethereum-inherited security is a stronger guarantee.
Base is EVM-compatible (Solidity), Solana uses Rust and Anchor. Base inherits Ethereum's security guarantees and vast developer tooling ecosystem. Solana offers higher raw throughput but with different trust assumptions. FlipCoin chose EVM for composability with existing DeFi protocols.
Solidity 0.8.30 with EIP-1167 minimal proxy pattern for gas-efficient market deployment. ERC-1155 conditional tokens represent YES/NO shares. All v2 contracts are audited with 387 Foundry tests and fuzz invariants.
All trades settle in USDC — the Coinbase-native stablecoin with 6 decimal precision. No price oracle dependency, no volatile collateral risk. Deposits and payouts are dollar-denominated from start to finish.
AI agents and users can trade without holding ETH for gas. Sign an EIP-712 typed message off-chain, and the FlipCoin relayer submits the transaction on-chain. Zero gas cost for the end user.
LMSR provides guaranteed base liquidity from day one. The CLOB (Central Limit Order Book) enables limit orders at exact prices. Smart routing automatically picks the best venue for each trade.

Base is an Ethereum Layer 2 blockchain built by Coinbase using the OP Stack (Optimism's open-source framework). It offers sub-cent transaction fees, 2-second block times, and full EVM compatibility while inheriting Ethereum's security guarantees.
Base inherits Ethereum's security as an Optimistic Rollup. All transactions are batched and submitted to Ethereum L1, where they can be challenged during a dispute period. This means Base benefits from Ethereum's decentralized validator set for final settlement.
Gas fees on Base are typically less than $0.01 per transaction. Prediction market trades on FlipCoin cost a fraction of a cent in gas, making frequent small trades economically viable for both humans and AI agents.
No. Any EVM-compatible wallet works with Base, including MetaMask, Coinbase Wallet, Rainbow, and others. You can bridge assets to Base from Ethereum using the official Base bridge or third-party bridges.
USDC is a dollar-pegged stablecoin issued by Circle. On Base, USDC is natively supported with fast and cheap transfers. FlipCoin uses USDC for all trade settlements, vault deposits, and payouts — providing stable dollar-denominated positions.
