# enable_eth_with_tokens

The Komodo DeFi Framework supports ETH(Ethereum) and many other EVM type platform coins like AVAX(Avalanche), BNB(Binance), FTM(Fantom), MATIC(Polygon), ONE(Harmony), ETH-ARB20(Arbitrum) . Additionally, it supports ERC20 tokens on the ETH chain and associated ERC20 like tokens on the rest of the platform coin chains. Using this method, you can enable a platform coin along with multiple ERC20 like tokens of the platform coin chain in a single command.

parameter	Type	Description
ticker	string	Ticker of the platform protocol coin. Options: `ETH`, `AVAX`, `BNB`, `FTM`, `MATIC`, `ONE`, `ETH-ARB20`
gas_station_url	string (optional for ETH/ERC20 and other gas model chains)	url of ETH gas station API (opens new window); The Komodo DeFi Framework uses eth_gasPrice RPC API (opens new window) by default; when this parameter is set, the Komodo DeFi Framework will request the current gas price from Station for new transactions, and this often results in lower fees
gas_station_decimals	integer (optional for ETH/ERC20 and other gas model chains)	Defines the decimals used to denominate the gas station response to gwei units. For example, the ETH gas station uses 8 decimals, which means that "average": 860 is equal to 86 gwei. While the Matic gas station uses 9 decimals, so 860 would mean 860 gwei exactly. Defaults to `8`
gas_station_policy.policy	string (optional for ETH/ERC20 and other gas model chains)	Defines the method of gas price calculation from the station response. `"MeanAverageFast"` will use the mean between average and fast fields. `"Average"` will return a simple average value. Defaults to `"MeanAverageFast"`.
mm2	integer	Required if not set in `coins` file. Informs the Komodo DeFi Framework whether or not the coin is expected to function. Accepted values are `0` or `1`
priv_key_policy	string (optional)	defaults to `ContextPrivKey`. value can be `ContextPrivKey`,`Trezor` when Komodo DeFi Framework is built for native platforms. value can be `ContextPrivKey`, `Trezor`, `Metamask` when the Komodo DeFi Framework is built targeting `wasm`
swap_contract_address	string	address of etomic swap smart contract
fallback_swap_contract	string	address of backup etomic swap smart contract
nodes	array of objects	objects describing each of the nodes to connect to
nodes.url	string	url of a node
nodes.gui_auth	bool (optional)	must be set to `true` for nodes run officially by the Komodo Platform team
rpc_mode	string (optional)	defaults to `Http`, value can be `Metamask` when the Komodo DeFi Framework is built targeting `wasm`
tx_history	bool	If `true` the Komodo DeFi Framework will preload transaction history as a background process. Must be set to `true` to use the my_tx_history method
erc20_tokens_requests	array of objects	objects describing each of the tokens to be enabled
erc20_tokens_requests.ticker	string	Ticker of the token to be enabled
erc20_tokens_requests.required_confirmations	integer	when the token is involved, the number of confirmations for the Komodo DeFi Framework to wait during the transaction steps of an atomic swap.
required_confirmations	integer (optional, defaults to `3`)	when the platform coin is involved, the number of confirmations for the Komodo DeFi Framework to wait during the transaction steps of an atomic swap
requires_notarization	boolean (optional, defaults to `false`)	If `true`, coins protected by Komodo Platform's dPoW security (opens new window) will wait for a notarization before progressing to the next atomic swap transactions step.
