breaking changes. Consider changing your code/scripts/configurations if you're
using anything mentioned here.
## Old RPC client APIs
A huge set of RPC client APIs was deprecated in versions 0.99.2 and 0.99.3
(August-September 2022), including very frequently used ones like
SignAndPushInvocationTx, AddNetworkFee, TransferNEP17. A new set of
invoker/actor/unwrap/nep17/etc packages was introduced decoupling these
functions from RPC client and simplifying typical backend code. Please refer
to rpcclient package documentation for specific replacements for each of these
APIs and convert your code to using them.
While a lot of the code is already converted to new APIs, old ones still can
be used in some code not known to us. Therefore we will remove old APIs not
earlier than May 2023, with 0.103.0 release.
## WSClient Notifications channel and SubscribeFor* APIs
Version 0.99.5 of NeoGo introduces a new set of subscription APIs that gives

that includes simple-signature accounts and multisignature accounts where
the client has one of the keys (in which case an invocation script is
created that pushes just one signature onto the stack).
10. Define lifetime for the fallback transaction. Let the `fallbackValidFor` be
the lifetime. Let `N` be the current chain's height and `VUB` be
`ValidUntilBlock` value estimated at step 3. Then, the notary node is trying to
collect signatures for the main transaction from `N` up to
`VUB-fallbackValidFor`. In case of failure after `VUB-fallbackValidFor`-th
block is accepted, the notary node abandons attempts to complete the main transaction and
tries to push all associated fallbacks. Use the following rules to define
`fallbackValidFor`:
- `fallbackValidFor` shouldn't be more than `MaxNotValidBeforeDelta` value.
- Use notary package's GetMaxNotValidBeforeDelta to check `MaxNotValidBefore` value.
11. Construct a script for the fallback transaction. The script may do something useful,
i.g. invoke method of a contract. However, if you don't need to perform anything
special on fallback invocation, you can use simple `opcode.RET` script.
12. Sign and submit P2P notary request. Use
[func (*Client) SignAndPushP2PNotaryRequest](https://pkg.go.dev/github.com/nspcc-dev/neo-go@v0.97.2/pkg/rpcclient#Client.SignAndPushP2PNotaryRequest) for it.
10. Sign and submit P2P notary request. Use
[func (*Actor) Notarize](https://pkg.go.dev/github.com/nspcc-dev/neo-go/pkg/rpcclient/notary#Actor.Notarize) for it.
- Use the signed main transaction from step 9 as `mainTx` argument.
- Use the fallback script from step 10 as `fallbackScript` argument.
- Use `-1` as `fallbackSysFee` argument to define system fee by test
invocation or provide any custom value.
- Use `0` as `fallbackNetFee` argument not to add extra network fee to the
fallback.
- Use the `fallbackValidFor` estimated at step 9 as `fallbackValidFor` argument.
- Use your account you'd like to send request (and fallback transaction) from
to sign the request (and fallback transaction).
`SignAndPushP2PNotaryRequest` will construct and sign a fallback transaction,
construct and sign a P2PNotaryRequest and submit it to the RPC node. The
resulting notary request and an error are returned.
`Notarize` will construct and sign a fallback transaction using `Actor`
configuration (just a simple `RET` script by default), pack both transactions
into a P2PNotaryRequest and submit it to the RPC node. It returns hashes of
the main and fallback transactions as well as their `ValidUntilBlock` value.
If you need more control over fallback transction use `Actor` options or
[func (*Actor) SendRequest](https://pkg.go.dev/github.com/nspcc-dev/neo-go/pkg/rpcclient/notary#Actor.SendRequest)
API.
After P2PNotaryRequests are sent, participants should wait for one of their
transactions (main or fallback) to get accepted into one of subsequent blocks.
