Which networks does sendBundle support?

Solana bundles route to Jito block engines through the Solana endpoint (/sol). On Ethereum, the shared JSON-RPC endpoint (/eth) does not accept eth_sendBundle: bundles go to a private forwarder you name in the path, /rpc/eth-private/ . Both use the same Triport API key: no separate relay accounts, no extra auth.

Do I need my own block-engine or relay account?

No. You submit the bundle over JSON-RPC with your Triport API key. On Solana the response carries the block engine's bundle id — a receipt for submission, not proof that it landed. On Ethereum the bundle goes to the private forwarder named in /rpc/eth-private/ ; what that forwarder does with it is its own decision, and Triport does not promise acceptance.

Does a submitted bundle always land?

No — acceptance and inclusion are different events. On Solana the Jito block engine runs an auction and your bundle competes on tip; on Ethereum a private forwarder may decline to include it. Treat the returned id as a receipt for submission and verify the result on-chain: by signature on Solana, by the bundle's transactions on Ethereum.

Which plan includes bundle submission?

sendBundle is available on Pro ($249/mo) and above, alongside advanced RPC capabilities across Solana, Ethereum, Polygon, BNB Smart Chain, Base, Tron, Robinhood Chain, Stellar and TON.

sendBundle: Jito bundles on Solana, private forwarders on Ethereum

Last updated: October 24, 2026

Why bundles

A bundle is an ordered group of transactions that is atomic if it lands— all or nothing, in sequence, invisible to frontrunners until inclusion. That is not a guarantee of inclusion.

On Solana the bundle enters a Jito block-engine auction with tip accounts, and the block engine decides whether it makes the block; on Ethereum it goes to a private forwarder that bypasses the public mempool and may simply not include it. Normally each rail needs its own integration, endpoints and auth. Through Triport both are one JSON-RPC call away.

Submit a bundle

curl https://triport.io/sol \
  -X POST -H 'Content-Type: application/json' \
  -H "x-token: $TRIPORT_API_KEY" \
  -d '{"jsonrpc":"2.0","id":1,"method":"sendBundle","params":[["<base64-tx-1>","<base64-tx-2>"]]}'
# the response carries the relay's bundle id — a receipt for an accepted
# submission, not an on-chain result. Verify the outcome afterwards.
# Ethereum: eth_sendBundle is not accepted on https://triport.io/eth.
# POST it to https://triport.io/rpc/eth-private/<forwarder-id> instead.

Pairs well with

Bundle strategies are timing games: the pre-execution stream shows order flow before execution, so your bundle is built on a recent picture of the chain.
