Prediction markets crossed $10 billion in monthly volume for the first time in March 2026. Perps protocols are processing billions daily across fragmented chains. Yet most of these platforms still force users through bridge-and-swap gymnastics before they can place a single trade.
The friction isn't just annoying. It's a leak in your conversion funnel. Builders integrating Chainflip's cross-chain settlement layer can accept deposits directly from Bitcoin, Ethereum, Solana, Arbitrum, and Polkadot Assethub, letting users fund positions in one step from whatever chain holds their assets.
Why Cross-Chain Deposits Matter for Onchain Apps
The numbers tell the story. Combined monthly trading volume on prediction markets like Kalshi and Polymarket rose from under $5 billion in September 2025 to about $24 billion in April 2026. TVL across crypto prediction markets hit above $550 million in January 2026.
That capital sits across every major chain. A trader holding SOL on Solana shouldn't need three separate transactions to fund a prediction market position that settles in USDC on Polygon. A Bitcoin holder shouldn't need to wrap, bridge, and swap just to open a perps position.
Cross-chain settlement collapses this into a single deposit flow. The user sends native assets from their chain of choice. The app receives the exact asset it needs on its settlement chain.
How Chainflip's Settlement Layer Works for Integrators
Chainflip operates as native settlement infrastructure rather than a bridge or solver network. When a user deposits BTC to fund a position, that Bitcoin moves directly through Chainflip's validator-secured protocol and arrives as USDC, ETH, or whatever asset your app needs.
The protocol has processed over $9 billion in lifetime volume across supported chains: Bitcoin, Ethereum, Solana, Arbitrum, and Polkadot Assethub. TRON support launched in June 2026. BNB Chain is coming soon.
For builders, integration happens through Chainflip's SDK and API. The core pattern is straightforward: your app requests a deposit address for the user's source chain, the user sends funds to that address, and Chainflip handles the cross-chain swap and delivers the output asset to your designated receiving address.
Integration Architecture: The SDK Approach
The Chainflip SDK exposes a few key functions that power deposit flows. Here's the high-level pattern for a prediction market accepting deposits:
Step 1: Request a deposit channel. Your backend calls the SDK to open a deposit channel specifying the source chain and asset (e.g., BTC on Bitcoin) and the destination chain and asset (e.g., USDC on Ethereum or Arbitrum).
Step 2: Generate the deposit address. Chainflip returns a unique deposit address on the source chain. This address is dedicated to that specific swap and routes funds through the protocol automatically.
Step 3: User sends funds. Your frontend displays the deposit address. The user sends native BTC, SOL, or ETH from their wallet. No approvals, no wrapped tokens, no bridge UI.
Step 4: Settlement completes. Chainflip's JIT AMM executes the swap. The output asset arrives at your app's receiving address. Your backend monitors the channel status via the API and credits the user's balance once settlement confirms.
The entire flow requires no user interaction with Chainflip directly. From their perspective, they deposit native assets and their app balance updates.
Practical Examples: Prediction Markets and Perps
Prediction Market Deposit Flow
Consider a Polymarket-style platform settling in USDC on Polygon. A user holds ETH on Arbitrum and wants to fund $500 in positions. With Chainflip integration:
User clicks "Deposit" and selects ETH on Arbitrum as their funding source
Platform requests a deposit channel: Arbitrum ETH → Polygon USDC
User sends ETH to the generated Arbitrum address
USDC arrives on Polygon at the platform's receiving address
Platform credits the user's trading balance
The user never leaves the prediction market interface. They never interact with a bridge.
Perps Protocol Margin Deposits
A perps protocol on Solana can accept margin deposits from Bitcoin holders. The trader sends BTC from their hardware wallet, and SOL or USDC arrives as margin collateral. This opens access to the entire Bitcoin-native user base without requiring those users to touch wrapped assets.
The same architecture works for any onchain app with a deposit flow: gaming platforms, NFT marketplaces accepting cross-chain payments, or DeFi protocols accepting collateral from multiple chains.
Partner Fee Revenue for Integrators
Builders integrating Chainflip can capture revenue on every deposit by setting a broker fee. This creates a sustainable revenue stream proportional to deposit volume.
The fee structure is transparent to users since it's included in the quoted exchange rate. Integrators receive their share directly on settlement.
Why Native Settlement Over Bridges or Solvers
Bridges require wrapped tokens and custody trust assumptions. Solver networks introduce counterparty risk and variable execution quality. Over $2 billion in bridge exploits have taught the industry that trust-minimized native settlement matters.
Chainflip's approach uses a decentralized custody model secured by validators. Users send and receive native assets directly. There's no wrapped token exposure for your users to worry about.
For builders, this translates to simpler integration (no token approval flows), better UX (users keep their native assets until the moment of deposit), and reduced support burden (no explaining why someone's wBTC is stuck in a bridge contract).
Getting Started
Integration begins with the Chainflip SDK. The documentation covers deposit channel creation, status monitoring, and best practices for handling edge cases like expired channels or partial fills.
Builders can test against Chainflip's Perseverance testnet before deploying to mainnet. The SDK handles the complexity of cross-chain communication, letting your team focus on your core product rather than infrastructure.
The settlement layer that's processed billions in volume is now available as composable infrastructure for any onchain app. Whether you're building the next prediction market, a perps protocol, or something entirely new, cross-chain deposits are one integration away.

What chains does Chainflip support for cross-chain settlement?
Chainflip currently supports Bitcoin, Ethereum, Solana, Arbitrum, Polkadot Assethub, and TRON. BNB Chain support is coming soon. Integrators can accept deposits from any of these chains and settle in any supported asset.
How do prediction markets integrate Chainflip for deposits?
Prediction markets use Chainflip's SDK to request deposit channels. When a user wants to fund their account, the platform generates a deposit address on the user's source chain. The user sends native assets, and Chainflip settles the output asset directly to the platform's receiving address.
Can integrators earn revenue on cross-chain deposits?
Yes. Builders can set a broker fee on each deposit processed through their integration. This fee is included in the exchange rate and paid directly to the integrator on settlement, creating a revenue stream proportional to deposit volume.
What's the difference between Chainflip settlement and using bridges?
Bridges require wrapped tokens and introduce custody trust assumptions. Chainflip uses native settlement secured by validators, meaning users send and receive native assets directly without wrapped token exposure. This reduces security risk and simplifies the user experience.
How long do cross-chain deposits take to settle?
Settlement time depends on the source chain's confirmation requirements. Bitcoin deposits take longer due to block confirmation times. Ethereum and Solana deposits typically settle within minutes. The SDK provides status monitoring so apps can update user balances as soon as settlement confirms.
