Application for Claude Max x20 #2

Good day,

This is an application to @deathwing for another Claude application. It ends on 30th April, and I want to proactively apply so I don't get downtime.

I am going to include the GitLab stats on what I have been working on for Hive. Please note that while the repos here are open-source on https://gitlab.syncad.com/hive/, they are far from ready. This is across 14 days. Special thanks to @blocktrades for creating the repos and to @gandalf for the runners in the pipeline (they have been a super value-add).

Tangible results??

I have managed to complete a bridge between Hive-Engine to Solana and back

H→V→S round trip — 2026-04-19

First end-to-end live run with all three chains on the happy path.
A user on Hive publishes a real tokens.transfer to the bridge
vault; velocity auto-mirrors and re-emits a BridgeOut; Solana
devnet mints wrapped STELLARUM. One user action, four on-chain
transactions, ~3.7s wall-clock from Hive detect to Solana confirm.

Setup

Sender account (Hive): spiritsurge
Vault account (Hive): velocity-bridge
Velocity namespace/token: astralwars / STELLARUM
Solana recipient pubkey: 21YhDTgH86WQKsDm4gEsFsARuwoQ3HppSqfi4GeaYvgc (devnet)
Token mint (Solana devnet): 2K1eWptkN3zmd5oCLSfLuFYsBUwBiHUYHpgY9WqghvHf
Relayer commit: fe1131b
Memo form: velocity:solana:<base58 solana pubkey>

What I did

One action. From spiritsurge on Hive, a real HE tokens.transfer
of 24 STELLARUM to velocity-bridge with memo:

velocity:solana:21YhDTgH86WQKsDm4gEsFsARuwoQ3HppSqfi4GeaYvgc

That's it. The rest is automatic.

Hive custom_json op

What the bridge did

Leg 1 — Hive: real HE transfer (spiritsurge → velocity-bridge)

Tx id: f6b7358444a746ea61254d03e31dfe25068c8112
Block: Hive 105649098
Op: custom_json with id=ssc-mainnet-hive, contractName=tokens,
contractAction=transfer. Signed under required_auths (active),
since HE rejects tokens.transfer signed with posting authority.
Vault balance on Hive-Engine credits 24 STELLARUM. Relayer's
deposit watcher picks up the op at confirmation depth 3.

Leg 2 — Velocity: BridgeIn credits `hive-transit`

Block: velocity height 3723
Action: BridgeIn { source_chain: "hive", source_tx_id: <20 raw bytes of Hive tx id>, to: "hive-transit", amount: 24, ... }
The hive-transit account isn't pre-registered; velocity
auto-creates accounts on first BridgeIn. By design it never
accumulates balance — the next leg debits the same 24.

velocity block 3723 BridgeIn

Leg 3 — Velocity: BridgeOut auto-hop from `hive-transit` → Solana

Block: velocity height 3724
Event hash: 8cbd0494d8c240542c33bf4b5fc43563e601cacc96e1e16c5f66860060e798b1
Action: BridgeOut { from: "hive-transit", amount: 24, destination: <32-byte Solana pubkey>, ... }
Immediately after the BridgeIn, the relayer's hive watcher POSTs
/bridge-out to velocity with the Solana destination parsed
from the memo. Velocity signs + emits the event; the forward-leg
pipeline picks it up through the SSE stream.

velocity block 3724 BridgeOut

Leg 4 — Solana devnet: mint 24 wrapped STELLARUM

Signature: 5wQeAC4mppDkfPJU622LGfx5QezaHN9gx6TusM6jtUCxsRgC9uPcnJsvGEThagWGLBdgNbEpwk6P2CbMVd93vteN you can click on the link here to view it on solana explorer.
Mints to the recipient's ATA for the STELLARUM mint. Memo
instruction on the same tx carries the human-readable
velocity-bridge: mint 24 STELLARUM to 21YhDTgH... line.

Status endpoint correlation

GET /bridge-out/8cbd0494.../status on velocity returns the Solana
side of the hop without the UI having to touch a Solana RPC:

  "event_hash": "8cbd0494d8c240542c33bf4b5fc43563e601cacc96e1e16c5f66860060e798b1",
  "status": "minted",

End-to-end: ~3.7s from deposit detection to Solana confirm.

There is also round trips and so on

I am not yet willing to completely divulge what this tech is and what it is meant to do. But I am making sure not to work on what @mahdiyari, who has accomplished a L1 bridge to Solana (this is an L2 bridge) or @magi.network is doing. (I will not be touching EVM)

We are all working towards the betterment of Hive. So my intention is to fill the gaps where possible. And trust me, for people wanting to build on Hive, there are many many many gaps so no need to fight over redundant gaps that everyone is trying to explore.

There is a whole section of work that has been done on my games that I am not even talking about, which is on a different gitlab.
