Breaking Changes

TSS and chain validation related queries have been moved from crosschain module to observer module:

• PendingNonces :Changed from /zeta-chain/crosschain/pendingNonces/{chain_id}/{address} to /zeta-chain/observer/pendingNonces/{chain_id}/{address} . It returns all the pending nonces for a chain id and address. This returns the current pending nonces for the chain
• ChainNonces : Changed from /zeta-chain/crosschain/chainNonces/{chain_id} to/zeta-chain/observer/chainNonces/{chain_id} . It returns all the chain nonces for a chain id. This returns the current nonce of the TSS address for the chain
• ChainNoncesAll :Changed from /zeta-chain/crosschain/chainNonces to /zeta-chain/observer/chainNonces . It returns all the chain nonces for all chains. This returns the current nonce of the TSS address for all chains

All chains now have the same observer set:

• ObserversByChain: /zeta-chain/observer/observers_by_chain/{observation_chain} has been removed and replaced with /zeta-chain/observer/observer_set. All chains have the same observer set
• AllObserverMappers: /zeta-chain/observer/all_observer_mappers has been removed. /zeta-chain/observer/observer_set should be used to get observers.

Observer params and core params have been merged into chain params:

• Params: /zeta-chain/observer/params no longer returns observer params. Observer params data have been moved to chain params described below.
• GetCoreParams: Renamed into GetChainParams. /zeta-chain/observer/get_core_params moved to /zeta-chain/observer/get_chain_params
• GetCoreParamsByChain: Renamed into GetChainParamsForChain. /zeta-chain/observer/get_core_params_by_chain moved to /zeta-chain/observer/get_chain_params_by_chain

Getting the correct TSS address for Bitcoin now requires providing the Bitcoin chain id:

• GetTssAddress : Changed from /zeta-chain/observer/get_tss_address/ to /zeta-chain/observer/getTssAddress/{bitcoin_chain_id} . Optional bitcoin chain id can now be passed as a parameter to fetch the correct tss for required BTC chain. This parameter only affects the BTC tss address in the response
