zeekay 0d8a06af7d dexvm: expose SubmitTx RPC (the C<->D keeper mempool seam)
The dexvm is a stateless atomic ZAP proxy whose ImportTx/RelayOrderTx/ExportTx
are deterministic block inputs, drawn from the proposer's pending pool. That pool
(ChainVM.SubmitTx -> pendingTxs + engine notify) was unreachable from outside the
process: CreateHandlers exposed only Ping/Status/Relay, so an off-chain keeper had
no way to inject the ImportTx that consumes the C->D atomic object the C-side
0x9999 SubmitSwapIntent writes, nor the settling RelayOrderTx. The full two-phase
seam therefore could not land a DEXFill.

This adds a dex.submitTx JSON-RPC method (api.Service.SubmitTx) that forwards
wire-encoded tx bytes to an api.TxSubmitter and returns the canonical
ids.Checksum256 tx id. The submitter is wired ONLY on the node path
(ChainVM.CreateHandlers builds the service with the ChainVM as submitter); the
inner VM's read-only CreateHandlers (standalone/test) reports ErrSubmitUnavailable.
Bootstrap-gated; admission/fee gate stays in ChainVM.SubmitTx. 6 unit tests cover
unavailable/not-bootstrapped/bad-hex/empty/success(verbatim+TxID)/submitter-error.

Lux Chains

Independent VM plugin binaries for the Lux Network.

Each directory builds to a standalone binary that the Lux node loads as a plugin via --plugin-dir.

Build

make            # build all VMs
make evm        # build one VM
make test       # test all

Install

lpm install evm
lpm install dexvm

Or copy binaries to ~/.lux/plugins/<vmid>.
