Relevant code snippet

async simulate(signerAddress, messages, memo) { const anyMsgs = messages.map((m) => this.registry.encodeAsAny(m)); const accountFromSigner = (await this.signer.getAccounts()).find((account) => account.address === signerAddress); if (!accountFromSigner) { throw new Error("Failed to retrieve account from signer"); } const pubkey = (0, amino_1.encodeSecp256k1Pubkey)(accountFromSigner.pubkey); const { sequence } = await this.getSequence(signerAddress); const { gasInfo } = await this.forceGetQueryClient().tx.simulate(anyMsgs, memo, pubkey, sequence); (0, utils_1.assertDefined)(gasInfo); return math_1.Uint53.fromString(gasInfo.gasUsed.toString()).toNumber(); }

The above function simulate can be invoked by SigningStargateClient which is a client created with an RPC connection URL and a key pair. Simulate transactions should not need the use of a key pair but only the use of a signer address should suffice. Note that in the function definition of the simulate, only the signer's public address is used which is how it should be. So please remove the requirement that the invoking object should need a private key.

The IBC Skills Matrix and Flow of Funds model we started to develop here is going to be very important to IBC go to market.

Any thoughts on how to get this into the website?
