 ### 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 oof the TSS address for the chain.
-* `ChainNoncesAll` :Changed from `/zeta-chain/observer/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.
+* `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.

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