Task: ETH/EVM Activation

API-v2task::enable_eth::init

task::enable_eth::init

Use this method for task managed activation of ETH/EVM coins & tokens. Refer to the task managed activation overview for activation of other coin types.

Arguments

Parameter* = required	Type	Description
erc20_tokens_requests*	`array of objects`	A list of standard TokensRequest objects.
fallback_swap_contract*	`string`	Address of backup etomic swap smart contract.
nodes*	`array of objects`	A list of standard CoinNode objects.
swap_contract_address*	`string`	Address of etomic swap smart contract
ticker*	`string`	Ticker of the platform protocol coin. Options: `ETH`, `AVAX`, `BNB`, `FTM`, `MATIC`, `ONE`, `ETH-ARB20`
gap_limit	`integer`	Optional. HD wallets only. The max number of empty addresses in a row. If transactions were sent to an address outside the `gap_limit`, they will not be identified when scanning.
gas_station_decimals	`integer` default: `8`	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.
gas_station_policy.policy	`string` default: `"MeanAverageFast"`	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.
gas_station_url	`string`	Optional. A url for gas station api.
get_balances	`boolean` default: `true`	Optional. If `false`, coin and token balances will not be returned in the response, and the response will be returned more quickly.
min_addresses_number	`integer`	Optional. HD wallets only. How many additional addreesses to generate at a minimum.
mm2	`integer`	Optional. Required if not set in `coins` file. Informs the Komodo DeFi Framework API whether or not the coin is expected to function. Accepted values are `0` or `1`
nft_req	`object`	Optional. Non-HD only. encapsulates the request parameters for NFT activation, including NFT provider configuration.
path_to_address	`object`	Optional. HD wallets only. A standard AddressPath object.
priv_key_policy	`string` default: `ContextPrivKey`	Optional. 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`
required_confirmations	`integer` default: `3`	Optional. When the platform coin is involved, the number of confirmations for the Komodo DeFi Framework API to wait during the transaction steps of an atomic swap
requires_notarization	`boolean` default: `false`	Optional. If `true`, coins protected by Komodo Platform's dPoW security will wait for a notarization before progressing to the next atomic swap transactions step.
rpc_mode	`string` default: `Default`	Optional. Value can be `Metamask` only when the Komodo DeFi Framework is built targeting `wasm`.
scan_policy	`string`	Optional. HD wallets only. Whether or not to scan for new addresses. Select from `do_not_scan`, `scan_if_new_wallet` or `scan`. Note that `scan` will result in multple requests to the Komodo DeFi Framework.
swap_v2_contracts	`object`	Optional. Must be provided if "use_trading_proto_v2" is true in your configuration. A standard SwapV2Contracts object.
tx_history	`boolean` default: `false`	Optional. If `true` the Komodo DeFi Framework API will preload transaction history as a background process. Must be set to `true` to use the my_tx_history method

Response

Parameter	Type	Description
status	string	A short indication of how the enabling is progressing.
details	object	Depending on the state of enabling progress, this will contain different information as shown in the responses below.

Possible status values while activation is in progress:

ActivatingCoin: The first step of activation. It does not require any action from the user.
RequestingWalletBalance: The first step of activation, while initial balances info is being requested. It does not require any action from the user.
Finishing: Activation process completed
WaitingForTrezorToConnect: Waiting for the user to plugin a Trezor device
FollowHwDeviceInstructions: Waiting for the user to follow the instructions on the device

Once complete, status will be Ok, and the details object will have the following structure:

Response

Parameter* = required	Type	Description
task_id*	`integer`	An identifying number which is used to query task status.
