Move REGEN between the Regen chain, Osmosis, Arbitrum and Base in ONE transaction the caller signs with their own wallet. Returns a live quote and the exact unsigned transaction; Skip Go's relayers carry every hop after the broadcast: no confirm step, nothing held by this server, free. Five routes: regen→arbitrum, regen→base and base→regen (axlREGEN through Axelar), plus regen→osmosis and osmosis→regen (a plain ICS-20 transfer over regen-1 channel-1 and osmosis-1 channel-8). This tool prepares that ICS-20 leg itself: zero toll, amount out equals amount in, one signed message, timeouts derived live by Skip, and no minimum send; on those two legs destination may be omitted, and the sender's own account re-encoded under the destination prefix is used (same key, same 20 bytes, no new wallet). Skip does now return a one-transaction route from Osmosis to Base, but it is a CosmWasm contract call rather than a plain ICS-20 transfer, and this tool prepares only ICS-20 transfers and Axelar sends, so it is not offered here; from Osmosis, route home first (osmosis→regen), then regen→base or regen→arbitrum from the regen1 address. Base USDC to REGEN and the reverse take two signed transactions and are not offered here either. Outbound sends from the Regen chain to Arbitrum or Base pay Axelar's flat per-transfer toll, which Axelar prices in dollars (about $0.19 to $0.23 measured across 2026-09-05 to 2026-09-08) and so floats in REGEN terms: measured between 94 and 175 REGEN across those days, on a transfer of any size, moving with both the REGEN price and the shape of the route Skip picks. It is quoted LIVE at call time and returned as quote.toll_regen. The response is authoritative; the figures in this text are approximate and there is no stable number to publish. On those Axelar routes send at least twelve times the live toll in one transfer (returned as quote.min_send_regen, which is null on the Osmosis legs because they have no minimum) and batch rather than dribble; a smaller send is refused with the live toll named. base→regen carries no REGEN toll: the prepared EVM transaction carries a small native ETH value instead, Axelar's fee as Skip quotes it (about $0.11 measured 2026-09-08, returned as sign_this.value and refused above $0.50), after one exact ERC-20 approval. Measured landing times with one key, every landing read from the destination chain on 2026-09-08: regen→osmosis under a minute, regen→base about 66 seconds, base→regen about 30 minutes because Axelar waits on Base finality before it approves an EVM to Cosmos call. After the broadcast, call bridge_status with the source chain and the transaction hash to follow it; a round trip through Base and back loses money at every size this tool prepares (the flat toll never crosses the small price spread), so move REGEN to where it is needed, never to trade the gap.
