wanchain-js-sdk

Class: CrossInvoker

CrossInvoker

Class representing a class to handle cross chain. SDK users can finish transfer coin or token from source chain to destination chain using this class. SDK users only provide source chain info., destination chain info., action (approve,lock,redeem,revoke) and the input(such as gas, gas limit, from address, to address, amount...),SDK can draw all the configuration used by system automatically

new CrossInvoker(config)

Parameters:
Name Type Description
config Object The merged config from user's configuration and sdk configuration.Users' configuration will override the configuration of SDK.
Source:
core/CrossInvoker.js

Members

config :Object

The merged config from user's configuration and sdk configuration.

ouboundInfoMap :Map.<string, Map.<string, Object>>

Destination chain's information including both coin info. and configuration of cross chain.
It is similar to [Destination chains info.]
Type:
  • Map.<string, Map.<string, Object>>
Source:
core/CrossInvoker.js

Methods

<async> init()

Init all the configuration used for cross chain.
step1: get tokens info. from api server.
step2: init all chains info.
step3: update token or coin symbol info. and the storemengroup related to this token or coin.
step4: init all the token or coin info. in source chains Map
step5: init all the token or coin info. in destination chains Map
Source:
core/CrossInvoker.js
Returns:
Type
Promise.<void>

<async> getTokensE20()

get ERC20 tokens from API server, the configuration of API server is located in ../../../../conf/config.js
Source:
core/CrossInvoker.js
Returns:
Type
Promise.<void>

initChainsNameMap()

Build all the coins and tokens information, this information is two-layer map structure.
first layer: key is chains name(such as 'ETH', 'WAN','BTC'), value is all the tokens and coins info. on this chain. second layer: key is the token unique address(currently, system use contract address of the tokens.
second layer: value is the info. about the token or coin.
Below is an example. [example for chainsName]
Source:
core/CrossInvoker.js
Returns:
- Two layers Map including all the tokens and coins chain information.
Type
Map.<string, MAP.<string, Object>>

initChainsSymbol()

Build promise array which is used to get the tokens' symbol and tokens' decimal
Source:
core/CrossInvoker.js
Returns:
- promise array about getting symbol
Type
Array

initChainsStoremenGroup()

Build promise array which is used to get the storemen group information related to the token or coin.
Source:
core/CrossInvoker.js
Returns:
Type
Array

initSrcChainsMap()

Init source chains map, this map is also a two layer map data structure.
first layer: key is chains name(such as 'ETH', 'WAN','BTC'), value is all the tokens and coins info. on this chain.
second layer: key is the token unique address(currently, system use contract address of the tokens.
second layer: value is the info. which used to finish cross token or coin from source chain to destination chain.
In this map, there is no WAN info., If the source chain in this map, it surely cross source chain to 'WAN'
If the destination chain in destination map (ouboundInfoMap), it surely the source chain is 'WAN'
Using this machine , system can decide the inbound (to 'WAN' chain)or outbound (from 'WAN')direction easily,
and in the next cross chain step
system gets rid of inbound or outbound decision, this sharply make service logic more easier.
Attention : in inboundInfoMap and in ouboundInfoMap ,there is no info. of 'WAN', because after system know
one side non 'WAN' chain, the other side chain is surely 'WAN'. Below is an example.
[example for source chains map]
Source:
core/CrossInvoker.js
Returns:
Type
Map.<string, MAP.<string, Object>>

initDstChainsMap()

Build destination chains info. It is similar to source chains info. [example for destination chains map]
Source:
core/CrossInvoker.js
Returns:
Type
Map.<string, MAP.<string, Object>>

isInSrcChainsMap(chainName)

Check the chainName whether in source chain Map or not , if yes, the cross chain is chainName->'WAN'
Parameters:
Name Type Description
chainName Object chainName ,chainName[0] the contract address of coin or token; chainName[1] the value of toke or coin chain's info.
Source:
core/CrossInvoker.js
Returns:
true: In source chains map, the destination chain is 'WAN'
false: Not in source chains map.
Type
boolean

isInDstChainsMap(chainName)

Check the chainName whether in destination chain Map or not , if yes, the cross chain is 'WAN'>chainName
Parameters:
Name Type Description
chainName Object chainName ,chainName[0] the contract address of coin or token; chainName[1] the value of toke or coin chain's info.
Source:
core/CrossInvoker.js
Returns:
true: In destination chains map, the source chain is 'WAN'
false: Not in destination chains map.
Type
boolean

<async> getSrcChainName()

Get the source chains info. supported by system.
Source:
core/CrossInvoker.js
Returns:
similar to this
Type
Promise.<(Map|*)>

getDstChainName(selectedSrcChainName)

Get the destination chains info. after SDK users have selected the source chain.
Parameters:
Name Type Description
selectedSrcChainName Object selectedSrcChainName ,selectedSrcChainName[0] the contract address of coin or token; selectedSrcChainName[1] the value of toke or coin chain's info.
Source:
core/CrossInvoker.js
Returns:
similar to this
Type
Map.<string, Map.<string, Object>>

<async> freshErc20Symbols()

Because during the system running, there is no Erc20 symbols added or deleted.
system can process this scenario automatically.
Source:
core/CrossInvoker.js
Returns:
Type
Promise.<void>

getKeyStorePaths(srcChainName, dstChainName)

When users provide source chain, and destination chain. System can get the right keystore path
for future use in cross chain process.
Parameters:
Name Type Description
srcChainName Object srcChainName ,srcChainName[0] the contract address of coin or token; srcChainName[1] the value of toke or coin chain's info.
dstChainName Object dstChainName ,dstChainName[0] the contract address of coin or token; dstChainName[1] the value of toke or coin chain's info.
Source:
core/CrossInvoker.js
Returns:

getKeyByBuddyContractAddr(contractAddr, chainType)

Get the buddy contract address, in chain info., there is two contract address. One is contract address
on the chain, for example ZRX is ERC20 token,ZRX token has a contract address on ETH chain; The other
contract address for token ZRX is the contract address on WAN chain.Here the buddy contract address is the
second contract address. System does not support get contract address on ETH by contract address on WAN

Since each storeman group has two address, one is the address on ETH chain, the other address is on WAN.
System can get the right address by below two parameters.
Parameters:
Name Type Description
srcChainName Object srcChainName ,srcChainName[0] the contract address of coin or token; srcChainName[1] the value of toke or coin chain's info.
dstChainName Object dstChainName ,dstChainName[0] the contract address of coin or token; dstChainName[1] the value of toke or coin chain's info.
Source:
core/CrossInvoker.js
Returns:
Type
Promise.<Array>
