When you swap SOL for BTC, something has to decide how that trade actually executes. Which pools? What order? How much slippage? The routing logic behind that decision separates native cross-chain protocols from bridge-based approaches in ways that directly affect what lands in your wallet.
This isn't about definitions. It's about mechanics: how route selection works, why JIT liquidity changes the math, and where bridge-based routing falls short.
Route Selection: The Core Problem
Every cross-chain swap faces the same fundamental question: what's the optimal path from asset A on chain X to asset B on chain Y?
Bridge-based systems typically solve this by wrapping the source asset, bridging the wrapped token, then swapping on the destination chain. A SOL-to-BTC swap might become: SOL → wSOL (wrap) → bridge to Ethereum → wBTC (swap) → unwrap or hold wrapped. Each step introduces fees, latency, and counterparty risk from the wrapped asset issuer.
Native routing protocols like Chainflip skip the wrapping entirely. The route selection logic operates on actual assets across chains, using a settlement layer that coordinates execution without synthetic intermediaries.
How Chainflip's JIT AMM Determines Optimal Paths
Chainflip routes swaps through USDC as the base pairing asset. This creates predictable two-leg routes for most swaps while maintaining deep liquidity pools.
For a SOL → BTC swap, the route is: SOL → USDC → BTC. Both legs execute on Chainflip's pools, coordinated by the State Chain.
The JIT (Just-In-Time) AMM mechanism is where routing efficiency gets interesting. When your swap enters the system, market makers have a brief window to provide liquidity specifically for your trade. They're competing to offer the best price, which compresses the spread below what static AMM pools can achieve.
Multi-Pool Routes in One Block
The JIT AMM processes all sells and buys for each pool sequentially, ensuring multi-pool routes complete in a single block. Your SOL → USDC → BTC swap doesn't wait for one leg to settle before the second begins. Both legs execute atomically, which eliminates the price drift that occurs when bridge-based swaps spread execution across multiple transactions and chains.
Bridge Routing: Where the Overhead Hides
Bridge-based cross-chain swaps typically involve three distinct operations: wrapping on the source chain, bridging the wrapped asset, and swapping (or unwrapping) on the destination.
Each operation has its own fee structure, confirmation requirements, and failure modes. The routing logic must account for bridge capacity, wrapped token liquidity on the destination chain, and the reliability of the bridge operator.
This creates routing complexity that native protocols avoid entirely. A bridge aggregator might route your SOL → BTC swap through multiple bridges and DEXs, optimizing for the best available rate across fragmented liquidity. But that optimization happens after accepting the fundamental constraint of wrapped assets.
The Speed Gap
Native routing processes the entire swap within Chainflip's protocol, secured by 150 validators. The only external confirmation required is the deposit transaction on the source chain and the final output on the destination chain.
Bridge-based routing adds confirmation times for wrapping, bridging (often requiring multiple block confirmations for security), and destination-chain execution. A straightforward swap can stretch from minutes to hours depending on bridge congestion and security parameters.
Fee Architecture: Fixed vs Layered
Chainflip charges a flat 0.10% protocol fee on all swaps. The JIT AMM spread and network gas are additional, but the fee structure is transparent and predictable.
Bridge-based routing stacks fees at each step: source-chain DEX fee, bridge fee (often 0.1%-0.5%), destination-chain DEX fee, and potentially wrap/unwrap fees. The total cost depends on which specific route the aggregator selects, making pre-swap fee estimation less reliable.
Slippage: Static Pools vs JIT Competition
This is where routing mechanics matter most for larger swaps.
Traditional AMMs price trades against a static curve. A large swap moves the price significantly, and that movement is your slippage. Bridge-based routes that end on destination-chain DEXs inherit this limitation.
JIT liquidity changes the dynamic. Market makers quote prices specifically for your swap size, competing for your order flow. The result is tighter execution, especially on larger trades where static AMM slippage would compound across multiple hops.
Chainflip has processed over $7.59 billion in cumulative swap volume, with the JIT mechanism consistently delivering execution quality that aggregators route to when optimizing for price.
Concrete Example: SOL → BTC Path
Here's how native routing handles a 100 SOL → BTC swap on Chainflip:
Deposit: User sends 100 SOL to a Chainflip deposit address
Route determination: Protocol identifies SOL → USDC → BTC as optimal path
JIT auction: Market makers compete to fill both legs
Execution: Both swaps execute in sequence within one block
Output: Native BTC sent to user's specified address
The entire process involves two on-chain transactions from the user's perspective: the deposit and receiving the output. No wrapping, no bridge confirmations, no intermediate token custody.
When Bridge Routing Makes Sense
Native routing excels when direct paths exist. Chainflip supports swaps between Bitcoin, Ethereum, Solana, Polkadot Assethub, and Arbitrum, with BNB Chain and Tron coming soon.
Bridge-based routing remains necessary for chains without native protocol support, or for moving specific wrapped assets that have utility on their destination chain. The tradeoff is accepting wrapped token risk in exchange for broader chain coverage.
The Routing Decision
When aggregators like Rango evaluate routes, they're comparing total output: your destination asset minus all fees and slippage. Native routing through protocols like Chainflip wins when the path is supported because it eliminates wrapping overhead and JIT competition delivers tighter spreads.
The routing isn't magic. It's just math on a simpler architecture.

What determines the route for a cross-chain swap on Chainflip?
Chainflip routes most swaps through USDC as the base pairing asset. When you swap SOL for BTC, the route is SOL → USDC → BTC, with both legs executed through JIT liquidity auctions where market makers compete to offer the best price.
How is native cross-chain routing different from bridge-based routing?
Native routing executes swaps directly between actual assets without wrapping. Bridge-based routing requires wrapping the source asset, bridging the wrapped token to another chain, then swapping or unwrapping. Native routing eliminates these intermediate steps, reducing fees, latency, and counterparty risk.
Why does JIT liquidity result in better swap execution?
JIT (Just-In-Time) liquidity lets market makers compete to fill your specific swap, quoting prices for your exact trade size. This competition compresses spreads below what static AMM pools can offer, especially for larger trades where traditional curve-based slippage would be significant.
How fast are multi-pool swaps on Chainflip?
Multi-pool routes on Chainflip complete in one block. The JIT AMM processes all sells and buys sequentially, so a two-leg swap like SOL → USDC → BTC executes atomically without waiting for intermediate settlement.
What are the fee differences between native and bridge-based routing?
Chainflip charges a flat 0.10% protocol fee plus JIT spread and gas. Bridge-based routing stacks fees at each step: source DEX fee, bridge fee (often 0.1%-0.5%), destination DEX fee, and wrap/unwrap costs. Native routing is typically more predictable and often cheaper for supported paths.
