• Spin up two local chains with Transient Storage support using anvil.
• Run node axelar-local/deploy.js to deploy Axelar contracts on both chains.
• Run node axelar-local/serve.js to deploy ERC20 tokens via AxelarGateway, and starts the relayer
• forge script script/DeployHook.s.sol:DeployTestChainA --rpc-url TestChainA --via-ir --code-size-limit 30000 --broadcast to deploy and initialize the hook on chain A
• forge script script/DeployHook.s.sol:DeployTestChainB --rpc-url TestChainB --via-ir --code-size-limit 30000 --broadcast to deploy and initialize the hook on chain B

Run forge test inside v4-template directory

testAddLiquidity: Test adding liquidity from the source chain. Validate that a portion of tokens are transfered to the bridge

testBridgeExecuteAndRangeBelow: Test receiving bridged liquidity on the destination chain when the range is below the current price. Validate the receiving callback works and balance changes are correct.

testBridgeExecuteAndRangeAbove: Test receiving bridged liquidity on the destination chain when the range is above the current price. Validate the receiving callback works and balance changes are correct.

testBridgeExecuteAndInRange: Test receiving bridged liquidity on the destination chain when current price is in range. Validate the receiving callback works and balance changes are correct.

setDestinationInfo: Sets the information regarding the destination chain, such as contract address, token addresses, and hook address. This must be configured before cross-chain liquidity provision

addLiquidity(PoolKey, IPoolManager.ModifyPositionParams): Used by the user to add liquidity to a pool. Initiates a lock operation to handle callbacks to perform the action

beforeInitialize: Initializes token symbols after the pool is created.

beforeModifyPosition: Enforces that the caller must be the hook contract itself when adding liquidity

_executeWithToken: Processes Axelar payload to handle token reception on the recipient chain and liquidity addition

_bridgeOut: Handles the actual token transfer across chains.

_takeDeltas: Transfers liquidity removed back to the user.

_settleDeltas: Transfers liquidity added to the pool manager.
