Question 1

How is this trade executed?

Accepted Answer

There are two directions. Pool → exchange: buy the token with a swap in the pool, send it to the exchange over the pool’s network and sell it on spot — deposits must be open on that network. Exchange → pool: buy on spot, withdraw to your own wallet on the pool’s network and sell into the pool with a swap — withdrawals must be open. The spread is locked in only once the coin arrives: while the network confirms, the price can move. How many confirmations the exchange waits for is shown in the row’s tooltip.

Question 2

What goes into the net for $1,000?

Accepted Answer

The spread at the best price minus the exchange taker fee, the pool impact for $1,000 (a buy or sell quote from the pool itself), gas (the swap plus the token transfer; for “exchange → pool” only the swap) and, for “exchange → pool”, the exchange withdrawal fee. Before a signal the net is recomputed at the average exchange book price for $1,000. Build an alert for this mode in builder — the “On-chain Spot Arb” condition.

Question 3

What do the “no data” and “not executable” marks mean?

Accepted Answer

We only present as executable what is computed at real size. “No data” — the net spread for $1,000 is not confirmed for this pair yet. “Not executable” — the calculation shows the pair does not pay off at $1,000: the net is below zero, the pool does not quote the trade, or the exchange book cannot fill the size. The “Executable” filter keeps only the working pairs.

Question 4

Which chains and DEXes are covered?

Accepted Answer

BNB Chain, Ethereum, Base, Arbitrum and Solana; PancakeSwap, Uniswap, Sushiswap, Aerodrome, Raydium, Meteora and Orca pools. The token in the pool is matched to the exchange by its contract address on the same network — a matching ticker does not count.
