Target
the target of the cross chain, such as eth
, erc20
, ibc/0/px
etc.
target specifies the operation after the cross chain, such as converting to ERC20 token, cross chain to other cosmos chain through ibc, or cross chain to external chain through crosschain module.
Target Rule
Empty
if target is empty, the cross chain token will be only processed by the cross chain module, and stay on f(x)Core.
for example:
if user call ethereum bridge contract sendToFx
method, the target is empty, the token will be transfer to address on f(x)Core
Prefix with ibc
if target is prefixed with ibc
, the token will transfer to other cosmos chain through ibc module.
for example:
if user call ethereum bridge contract sendToFx
method, the target is ibc/0/px
, the token will be transfer to address on pundix chain
if user call f(x)Emv CrossChain contract crossChain
method, the target is ibc/0/px
, the token will be transfer to address on pundix chain
Module Name
if target equals to module name, the token will process by the module, and send to external chain or convert to f(x)Core ERC20 token.
for example:
if user call ethereum bridge contract sendToFx
method, the target is erc20
, the token will be transfer to f(x)Core ERC20 token.
if user call f(x)Core CrossChain contract crossChain
method, the target is eth
, the token will be transfer to ethereum chain.

FX is the native token, when cross chain to fx-core, no need to convert to ERC20, so the target is ""
, if other token, need to convert to ERC20, so the target is erc20

ibc/{channel-id}/{address-prefix}
if cross chain to other cosmos-chain, need to specify channel-id and address-prefix in target, for example: cross chain to cosmos-hub, need to find the channel-id of cosmos-hub on f(x)Core, and the address-prefix of cosmos-hub, then fill in the target in the format of ibc/{channel-id}/{address-prefix}
, if the channel-id of cosmos-hub on f(x)Core is channel-8
, and the address-prefix is cosmos
, then the target is ibc/8/cosmos
