 Cross chain transfers using Axelar General Message Passing (GMP)
 More info about cosmos GMP find [here](https://docs.axelar.dev/dev/cosmos-gmp)
 
+## Axelar IBC Memo
+
+```go
+type Memo struct {
+    SourceChain   string `json:"source_chain"`
+    SourceAddress string `json:"source_address"`
+    Payload       []byte `json:"payload"`
+    Type          int64  `json:"type"`
+}
+```
+
+When user wants to execute leverage supply or supply collateral or liquidate transaction using Axelar GMP , user have to send `Payload=[]byte(Msg)` in `Memo` ,
+in below example contract change [payload](https://github.com/axelarnetwork/evm-cosmos-gmp-sample/blob/main/native-integration/multi-send/solidity/contracts/MultiSend.sol) feild and version ,for now we are supporting `uint32(2)` version.
+
+## Supported Leverage Msgs through Axelar GMP
+
+### Supply the asset
+
+```go
+type MsgSupply struct {
+    // Supplier is the account address supplying assets and the signer of the message.
+    Supplier string     `protobuf:"bytes,1,opt,name=supplier,proto3" json:"supplier,omitempty"`
+    Asset    types.Coin `protobuf:"bytes,2,opt,name=asset,proto3" json:"asset"`
+}
+```
+
+### Supply and Collateral Msg
+
+```go
+type MsgSupplyCollateral struct {
+    // Supplier is the account address supplying assets and the signer of the message.
+    Supplier string     `protobuf:"bytes,1,opt,name=supplier,proto3" json:"supplier,omitempty"`
+    Asset    types.Coin `protobuf:"bytes,2,opt,name=asset,proto3" json:"asset"`
+}
+```
+
+### Liquidate Msg
+
+```go
+type MsgLiquidate struct {
+    // Liquidator is the account address performing a liquidation and the signer
+    // of the message.
+    Liquidator string `protobuf:"bytes,1,opt,name=liquidator,proto3" json:"liquidator,omitempty"`
+    // Borrower is the account whose borrow is being repaid, and collateral consumed,
+    // by the liquidation. It does not sign the message.
+    Borrower string `protobuf:"bytes,2,opt,name=borrower,proto3" json:"borrower,omitempty"`
+    // Repayment is the maximum amount of base tokens that the liquidator is willing
+    // to repay.
+    Repayment types.Coin `protobuf:"bytes,3,opt,name=repayment,proto3" json:"repayment"`
+    // RewardDenom is the denom that the liquidator will receive as a liquidation reward.
+    // If it is a uToken, the liquidator will receive uTokens from the borrower's
+    // collateral. If it is a base token, the uTokens will be redeemed directly at
+    // a reduced Liquidation Incentive, and the liquidator will receive base tokens.
+    RewardDenom string `protobuf:"bytes,4,opt,name=reward_denom,json=rewardDenom,proto3" json:"reward_denom,omitempty"`
+}
+```
