From YouTube: Message Sending Fun

Description

A demo of some big UX improvements to the Lotus message send CLI command that should land soon!

A

Speaking of following that uh cool you're up next, uh to talk about more message, sending fun.

B

uh Yeah message sending fan: uh let's call it that so yeah so last week I roughly showed this, though, which was roughly because it of course didn't work due to demo effect but yeah.

B

I want to send a message: uh there's a whole bunch of like parameters set to replicate like because I'm running it on devnet uh to replicate base fee being high and, uh like you, your max fee, not allowing higher base fee so yeah, uh I tried to send message, and normally it would just send the message and wouldn't tell you anything that your message is not going through. Probably never uh so, uh and now it tells me oh, like this message uh one.

B

I have insufficient bars for this message because I'm trying to send han fill, even though I have exactly 100 fill in this account and secondly, my gas fee cup is less less than the base fee and secondly, there is a message in my mempool, which uh can I hide this yes, I can, which already has an insufficient balance, but yeah.

B

Let's say I want to, even though I want to move forward, but I can I want to solve the issue of the gas v cap, so I can press enter or type in yes or why, and it will show me allow me to adjust the fi cap and I can press plus or minus to adjust the v cup. I can press s to use like suggested pickup and also I can just enter a fee cup I want to.

B

uh If you get maximum fee, I want to use- and it tells me like okay, so I'm entering current maximum fee, which is like the maximum fee, I'm willing to pay for this message and yeah and tells me like what the current base fee is and what my resulting fee cup is so.

A

B

uh That's the start of it and then I can either exit with escape or control c or confirm with enter and because there are some uh other checks that are still failing. It asks me for confirmation whether I really want to send this message, and I tell it yes and I send this message, but now this message is blocking my mampo and let's say I sent 10 messages after that, and I want to resolve, resolve the problems so or we can just send a message that will won't be blocking and yeah.

B

Let's do that so now I'm sending, I will send like a normal message that would go through if that previous message wasn't here, uh I still get an insufficient balance, because the previous messages have caused this message to have insufficient balance because I'm sending hundred falcon, even though, in my account I have 500 that will tell it to go through and then now I can open autosample manage. I see a list of all my addresses. I was using this one and I now see all the messages that are sitting in my maple.

B

I have no minor running so it's easier for me to gather more messages in memphis, otherwise they would go through until blocked and I can see okay, uh this message has a failing check. So, let's check it out and it tells me oh, it has insufficient balance. Okay, so, like the simplest way to solve it would be to replace this message. Let's say I made a mistake and I want to just remove this message and I can tell to do so by pressing pressing n.

B

I just uh I just tell it to replace the message with no operation message, which is very small message that that's going to send zero file coin to to t099 and yeah. It asked me if I want to confirm uh this message. I can tell it yes and it replaced it as you can see. The message now goes instead of to to the address handicap in nnq. It goes to t099, and I can do the same with this message, so I can replace this message with no up and now.

B

The last message is okay, because, because it's unlocked now and yeah, I can also reprice messages using the same ui we saw during sending process. I can also apply on messages in in this in this flow so yeah I can increase or like let's say this message is super important to me and I want to spend currently 20 dollars on it. I can do so and we can see that yeah it's pickup is super high. I should probably display the max fee on it, but yeah, so that's roughly it from message management, uh so yeah.

B

This also is also integrated, currently into all uh multisig commands. So if you're using multisig, you will encounter the same. Oh your message has some issues flow in future. It would will be implemented in markets, which means uh topping up your markets account to make search deals and of payment channels, but currently they are handled uh very differently. So we didn't do that. Yet, maybe in a follow-up yeah any questions.

A

uh Yeah, can you can you confirm that the isis message actually landed on chain because that's kind of your success metric here it does you remove the block, uh the last one uh you had it on the green screen.

B

Yeah, oh, I can guarantee. If I started miner, it would land right now.

A

A

How much work was this.

B

uh um A bit like uh the ui itself like designing the ui doing the ui wasn't the hardest part like the big part, was writing the checks which, in back part, visa, wrote but then integrating the ui with lotus and then agreeing lotus to work with the ui and agreeing with our cli to work with dui was was a bit of a hell climb, yeah jennifer, just to respond to you.

B

I could it's cheaper to send it to t099 so yeah and for small messages is significantly cheaper, like it's like close to 10 or 20 cheaper, so might as well. Send it to 0.99.

B

Any more questions I have.

C

A quick one hopefully yeah is there. Are there checks that um would you'd be allowed to try and send the message and it could still go through if it failed.

B

So now there are no texts that would fail and the message would still right away landlord chain like if they basically, for example, decreased yeah. It could, after some time period of time, a landowner chain, but yeah we used to we used to have I've currently disabled. It had one check which was like. Oh, is your message saved to london check which is like uh if, if the base fist is rising at maximum pace in next 20 blocks, it can still it can still unblend, but it led to some false positives.

B

So I disabled that check for for right for right now. So, ideally, if everything is going, okay right, as my my input is okay right now for this uh center address. If I press enter, I don't get any.

B

B

uh Any more questions.

B

uh Yeah, it does uh jennifer, doesn't care.

D

Yeah we tried this with any um folks in the wild um like giving this to the minor x minors or anything like that to.

B

D

How much they rave over it.

B

Not really because the integration path with lotus we're still waiting on uh like this is blocked currently on v1 api work in lotus. So there's no currently no clear way to deploy it in in on clearly, unless master like, I could give them my branch, but.

B

Although the integration, as I was told by magic, should land in either either today or late into next week,.

A

Yeah, it's been approved like two times already with magic swing.

B

A

um uh But yeah deep flags that, in general, the minor x fellows, are happy to can be given like custom branches, so uh certainly an option but yeah um cool any other. Any other questions, just a bunch of people saying super cool in the chat um yeah. I'm sure everyone already acknowledges this, but like the the hypothetical that cougars was describing, are not hypotheticals in terms of oh, you set the wrong field here and then you get stuck that's something. That's happened over and over again to partners to pl employees to lotus.

B

A

This is definitely useful, um but cool thanksgiving.

B

I did it myself few times while using like, like you, don't even do it on purpose, because, but like your, your max v default is slow enough, that, like bigger operations like multi-stick operations, stop going through right. So yeah.

A
