Hi, welcome to our developer documentation. Here, you will find everything about AssetMantle. Stay tuned, we will update this docs gradually.
This section includes examples related to mantle-1 chain. Gradually, we will update this section thoroughly.
-
Generate an address from mnemonics
// JavaScript Examples import { DirectSecp256k1HdWallet } from "@cosmjs/proto-signing"; import { stringToPath } from "@cosmjs/crypto"; const mnemonic = "<your mnemonic>"; const wallet = await DirectSecp256k1HdWallet.fromMnemonic( mnemonic, { prefix: "mantle" }, stringToPath("m/44'/118'/0'/0/0") ); const account = await wallet.getAccounts(); console.log(account[0].address); // result: Output Structure mantle1g9szh5sg0kps4k30343kswgvlus2wn7v2ecfkk;
-
Send your transaction to mantle address
// JavaScript Examples import { DirectSecp256k1HdWallet } from "@cosmjs/proto-signing"; import { stringToPath } from "@cosmjs/crypto"; import { assertIsDeliverTxSuccess, SigningStargateClient, calculateFee, GasPrice, coins, } from "@cosmjs/stargate"; const mnemonic = "<your mnemonics here>"; const wallet = await DirectSecp256k1HdWallet.fromMnemonic( mnemonic, { prefix: "mantle" }, stringToPath("m/44'/118'/0'/0/0") ); const account = await wallet.getAccounts(); const rpcURL = "https://rpc.assetmantle.one"; const rpcClient = await SigningStargateClient.connectWithSigner( rpcURL, wallet ); const recipient = "<reciver account address>"; const tokens = coins(1000, "umntl"); const gasFee = { amount: [ { denom: "umntl", amount: "0", }, ], gas: "200000", }; const txHashOut = await rpcClient.sendTokens( account[0].address, recipient, tokens, gasFee, "Transaction" ); assertIsDeliverTxSuccess(txHashOut);
-
Create new account on mantle-1 chain
// JavaScript Examples import { DirectSecp256k1HdWallet } from "@cosmjs/proto-signing"; import { stringToPath } from "@cosmjs/crypto"; const wallet = await DirectSecp256k1HdWallet.generate( 24, { prefix: "mantle" }, stringToPath("m/44'/118'/0'/0/0") ); console.log(wallet.mnemonic); const account = await wallet.getAccounts(); console.log(account[0].address); // result: Output Structure become whale old bleak goose leader vivid armed digital shuffle fire input donor perfect patch found illegal basic vanish feel man try fall cactus mantle1y7pmvzpgwfvvq6zupqjfcgntauc90ww73wxs8s
So, this section includes use cases of mantleNode, RPC Endpoint, Websockets, REST, or LCD Endpoint.
🚀 NOTE: Please, make sure you download essential packages, to test below examples. Packages: go, jq, gcc, make, curl, git, vim and mantleNode (from github).
-
Initialize the default configurations
# --keyring-backend and --home flags are optional mantleNode init "<your-moniker-name>" --chain-id "mantle-1" --home "/home/node/.mantleNode
-
Create keys on your remote system
# --keyring-backend and --home flags are optional mantleNode keys add "<key-name>" --keyring-backend "os" --home "/home/node/.mantleNode"
-
Recover your keys with mnemonics on your remote system
# --keyring-backend and --home flags are optional mantleNode keys add "<key-name>" --recover --keyring-backend "os" --home "/home/node/.mantleNode"
-
Or, if you want to import your keys from private keyfile
# --keyring-backend and --home flags are optional mantleNode keys import "<key-name>" "<key-file>" --keyring-backend "os" --home "/home/node/.mantleNode"
-
Query your account balance
mantleNode query bank balances "<address>" --chain-id "mantle-1" --node "https://rpc.assetmantle.one:443" --output "json"
-
Query your account (address, number, sequences, and pub_key)
mantleNode query account "<address>" --chain-id "mantle-1" --node "https://rpc.assetmantle.one:443" --output "json"
-
Subscribe an event which output new block events
- Wesocket Example
{ "jsonrpc": "2.0", "method": "subscribe", "params": ["tm.event='NewBlock'"], "id": 1 }- Result Output Structure (snipped ...)
{ "jsonrpc": "2.0", "id": 1, "result": { "query": "tm.event='NewBlock'", "data": { "type": "tendermint/event/NewBlock", "value": { "block": { "header": { "version": { "block": "11" }, "chain_id": "mantle-1", "height": "1494200", -
Subscribe an event which output latest transaction events
- Websocket Example
{ "jsonrpc": "2.0", "method": "subscribe", "params": ["tm.event='Tx'"], "id": 1 }- Result Output Structure (snipped ...)
{ "jsonrpc": "2.0", "id": 1, "result": { "query": "tm.event='NewBlock'", "data": { "type": "tendermint/event/NewBlock", "value": { "block": { "header": { "version": { "block": "11" }, "chain_id": "mantle-1" -
Subscribe an event which output latest incoming transactions to a particular address events
- Websocket Example
{ "jsonrpc": "2.0", "method": "subscribe", "params": [ "tm.event = 'Tx' AND transfer.recipient = 'mantle1907n5d2xwy3av597y6347dsc2ktpl2d9u0j4tu'" ], "id": 1 }-
Result Output Structure (snipped ...)
{ "jsonrpc": "2.0", "id": 1, "result": { "query": "tm.event = 'Tx' AND transfer.recipient = 'mantle1907n5d2xwy3av597y6347dsc2ktpl2d9u0j4tu'", "data": { "type": "tendermint/event/Tx", "value": { "TxResult": { "height": "1468096", "index": 2, "tx":

We provide following endpoints to help developers for integration
| Protocol | Endpoints |
|---|---|
| RPC | https://rpc.assetmantle.one |
| REST | https://rest.assetmantle.one |
| GRPC | grpc://grpc.assetmantle.one |
| WSS | wss://rpc.assetmantle.one:443/websocket |
To use statesync, change the following under config.toml
[statesync]
enable = true
rpc_servers = "https://rpc.assetmantle.one:443,https://rpc.assetmantle.one:443"
trust_height = 0
trust_hash = ""
trust_period = "112h0m0s"and use a trusted height from the rpc, recent height will work as well
curl -s https://rpc.assetmantle.one/status | jq '.result .sync_info | {trust_height: .latest_block_height, trust_hash: .latest_block_hash} | values'This section includes validator contributions:
