Zap Migrate — Move Between Pools

Use the ZaaS API to migrate an existing liquidity position from one pool to another in a single transaction.

Zap Migrate — Move Between Pools

Zap Migrate lets users move their liquidity from a source pool (or position) to a destination pool without manually removing liquidity, swapping, and re-depositing. This is useful for rebalancing across DEXes, fee tiers, or price ranges.

Prerequisites

• Know the source position (positionId or tick range + pool) to migrate from.

• Know the destination pool and target tick range.

• Approve the KSZapRouterPosition contract on the source token if required.

Curve and Balancer pools can be used as the source of a migration but not as the destination. See Supported Chains & DEXes.

Flow Overview

GetMigrateRoute  →  (user reviews preview)  →  BuildMigrateRoute  →  send transaction

Step 1 — Preview the Migrate Route

Call GET /api/v1/migrate/route to preview the migration before the user confirms.

Key request parameters:

Parameter	Description
dexFrom	Source DEX ID — see DEX IDs
dexTo	Destination DEX ID
poolFrom.id	Source pool address
poolTo.id	Destination pool address
position.id	Source position NFT ID
position.tickLower / tickUpper	Target tick range in the destination pool
slippage	Slippage tolerance in basis points

Key response fields:

Field	Description
poolDetails	Pool info after zapping for destination pools
positionDetails	Estimated new position in the destination pool
zapDetails.priceImpact	Combined price impact of the migration
route	Encoded route to pass to BuildMigrateRoute

Step 2 — Build the Transaction

Call POST /api/v1/migrate/route/build with the route from Step 1:

curl -X POST "https://zap-api.kyberswap.com/{chain}/api/v1/migrate/route/build" \
-H "content-type: application/json" \
-H "x-client-id: your-client-id" \
-d '{
  "sender": "0xYourAddress",
  "recipient": "0xYourAddress",
  "route": "<route from GetMigrateRoute response>",
  "deadline": 1800000000
}'

Step 3 — Send the Transaction

const tx = await signer.sendTransaction({
  to:    buildResponse.routerAddress,
  data:  buildResponse.calldata,
  value: buildResponse.value,
  gasLimit: getMigrateRouteResponse.gas * 2,
});
